Upgrade under work, many things changes when moveing from precise to trusty.
 +
Same whit notes, those are mixed now. Below precise notes and trusty note's

Cluster Kurrola desing targets:
 +
easy to manage ( [[webmin]] and [[LTSP]] are tested and compared ) ,
 +
get parallel solvers work ( [[bind9]],[[dhcp]],[[nfs4]] )
 +
giganet whit IP4,
 +
stabilize system ( [[Twin Machine]] , [https://sites.google.com/site/jpsdatareviewstheboy007/4gcantennamobileinternet:"4G Cantenna mobile internet Antenna,.."]
 +
server to work outside world at IPV6 and inside IPV4 / IPV6 ([[wwdial]],[[hostapd]],[[radvd]],[[shoreline]],[[shoreline6]])
 +
basic servers ( [[mysql]], [[postresql]], [[apache2]], [[mediawiki]], [[mythweb]], [[calibre]] )
 +
and
 +
wlan services to workstations
 +
 
 +
To get parallel software like [[elmerfem]] and [[openfoam]] to work correctly you need full stack ( name services DNS and routing ) of network service and as learnt at practice at twin machine configuration. Twin machine configuration for [[DHCP]] ( both ipv4 and ipv6 ), BIND9 ( master and slave ). [[BIND9]] namaserice is needed to have stable routing even connection to global internet breaks. DHCP is used to networkboot and network address managment. To get IPV6 and IPV4 filtered and routed correctly [[Shoreline]] and [[Shoreline6]] are simple tool to configure firewall to Linux kernel. You need device level softaware like wvdial to get 4G modem/router to talk whit server routing and brdegeing software as well hostapd to open wlan services. To manage configuration of servers as well workstations [[webmin]] is good tool. To get network working well whit software you need common usernamre as well password base to get communication work between machines and services like [[NFS4]] and [[rsh-redone]].
 +
 
 +
For post prosessing you need [[Paraview]] as well support for 3d mouse. That's possible by building Praview 4.0 from sources whit [[vrpn]] and [[hidapi]].
 +
 
 +
Cluster Kurrola ( MPI4YOU ) base parameters:
 +
 
 +
/mpi3 is directory shared via NFS4 to all nodes
 +
/mpi3/B3 Build Script's for version 3
 +
/mpi3/S3 Source Code version 3
 +
/mpi3/C3 Code Verion 3
 +
 
 +
Each node has Ubuntu 12.04 LTS ( Long Term Suport version, no need to change OS for 7 years )

Installing NetworkManager is simple way to get all right for single machine network. I got big supprise when I understood how complex it come to setup STABILE beawulf parallel network to home, you need to setup all network components.
 +
 
 +
 
 +
Ubuntu 12.04 have much automation at protocol stack, it finds devices when connected ([udev]) and most cases setups hardware drivers and creates device like eth and ttyUSB. At Cluster Kurrola Installation NetworkManager is totaly removed due instability and some server software incompatibility issues ([[calibre]],[[mpich3]],[[rsh-redone]]). What have to do is to glue kernel IPV4 and IPV6 part's together whit devices and give correct parameter's to devices for operation.

Forcing IPv4 when sending to Gmail
 +
 
 +
If we want to force postfix to use IPv4 instead IPv6 when sending to Gmail, we need to add a line in the main configuration file of postfix like so
 +
1
 +
2
 +
 +
$ sudo nano /etc/postfix/main.cf
 +
transport_maps = hash:/etc/postfix/transport
 +
 
 +
Let’s create this new file and add a new entry in the transport table. Basically, we fore mail for gmail.com to use smtp-ipv4 (which we have to define later, see below)
 +
1
 +
2
 +
 +
$ sudo nano /etc/postfix/transport
 +
gmail.com smtp-ipv4:
 +
 
 +
Here comes the key part. We create a new rule for our new entry and define to use IPv4 protocol explicitly when this rule applies:
 +
1
 +
2
 +
3
 +
 +
$ sudo nano /etc/postfix/master.cf
 +
smtp-ipv4 unix .. .. .. .. smtp
 +
-o inet_protocols=ipv4
 +
 
 +
We need to run the postmap command after the change and reload postfix
 +
1
 +
2
 +
 +
$ sudo postmap /etc/postfix/transport
 +
$ sudo postfix reload
 +

== MYSQL to SSD==
 +
 
 +
Whit TokuDB prevent sw&hw buffering:
 +
 
 +
hdparam -W0 /dev/SDD
 +
 
 +
Mysql run on two SSD at server mpi1 and mpi2, asyncronouse mode mpi2 as master.
 +
 
 +
Innodb's can not be copyed palce to another, directory name must be same if so you can copy from system to other.
 +
So do mysqldump, setup new storage system and re-install databases.
 +
 
 +
 
 +
Setup:
 +
 
 +
/etc/mysql/my.cnf  datadir=<sdd dir>
 +
datadir        = /media/dbs/mysql
 +
 
 +
/etc/apparmor.d/abstractions/mysql

HowTo: Repair Ubuntu dpkg status file
 +
My Ubuntu 10.04.02 installs starting losing /var/lib/dpkg/status, and you can't update without it...
 +
Thanks to capink, but I ended up re-installing anyway so unfortunately losing this file you are near the end of the line.
 +
 
 +
http://ubuntuforums.org/archive/index.php/t-474587.html
 +
Using the script below will generate a new status file in your current directory (usually your home dir). Use this file in place of your status file after backing it up:
 +
 
 +
#!/bin/bash
 +
 
 +
get_control_info ()
 +
{
 +
for i in /var/lib/apt/lists/*_Packages
 +
do
 +
sed '/Package: '"$1"'$/,/^$/!d' $i
 +
done
 +
}
 +
 
 +
for i in /var/lib/dpkg/info/*.list
 +
do
 +
package_name=`basename $i | sed 's/.list$//'`
 +
get_control_info $package_name >> status-new
 +
done
 +
 
 +
sed -i -e '/^Filename: .*/d' -e '/^MD5sum:/d' -e '/^SHA1:/d' -e '/^SHA256:/d' status-new
 +
sed -i '/^Package: /a\Status: install ok installed' status-new

LDAP Single-Sign-On with Webmin on Ubuntu 12.04 HOWTO
 +
Submitted by hswong3i on Tue, 2013-01-08 00:01
 +
 
 +
In order to setup a LAMP cluster we usually need a way to share the master server uid/gid with other else member servers, for whatever NFS shared home directory, or running Apache2 + PHP5 in suexec style. Using LDAP + Webmin can simplify this Single-Sign-On (SSO) need in a handy way.
 +
 
 +
This HOWTO will guide you though installation of Webmin and OpenLDAP server, then use it as SSO between 2 server with nss-pam-ldapd. First of all let's fouce on making it works, and then enhence it with better security.
 +
Server Requirement
 +
 
 +
In this example let's assume we have 2 servers: dev6c1 and dev6c2, with domain name "localdomain" and IP information as below:
 +
 
 +
172.24.145.25 dev6c1.localdomain dev6c1
 +
172.24.145.26 dev6c2.localdomain dev6c2
 +
 
 +
Where dev6c1 will be the master for OpenLDAP, where dev6c2 will be slave that using nss-pam-ldapd as SSO.
 +
Install Webmin Manually
 +
 
 +
Simply execute following commands:
 +
 
 +
cat >> /etc/apt/sources.list.d/virtualmin.list <<-EOF
 +
deb http://download.webmin.com/download/repository sarge contrib
 +
deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib
 +
deb http://software.virtualmin.com/gpl/ubuntu/ virtualmin-precise main
 +
deb http://software.virtualmin.com/gpl/ubuntu/ virtualmin-universal main
 +
EOF
 +
 
 +
wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -
 +
wget -q http://software.virtualmin.com/lib/RPM-GPG-KEY-virtualmin -O- | sudo apt-key add -
 +
wget -q http://software.virtualmin.com/lib/RPM-GPG-KEY-webmin -O- | sudo apt-key add -
 +
 
 +
aptitude -y install ubuntu-extras-keyring && \
 +
aptitude update && \
 +
aptitude -y full-upgrade && \
 +
tasksel install openssh-server && \
 +
tasksel install server && \
 +
tasksel install mail-server && \
 +
aptitude -y install usermin webmin && \
 +
aptitude update && aptitude -y full-upgrade && aptitude autoclean && aptitude clean
 +
 
 +
Install OpenLDAP
 +
 
 +
Execute following commands at dev6c1 as OpenLDAP master:
 +
 
 +
aptitude -y install slapd libnet-ldap-perl ldap-utils
 +
 
 +
Don't care about the initial question, just feel free to answer them, as we will now reconfigure it with:
 +
 
 +
    dpkg-reconfigure slapd
 +
        Omit OpenLDAP server configuration? No
 +
        DNS domain name: localdomain
 +
        Organization name: localdomain
 +
        Administrator password: (your password)
 +
        Database backend to use: HDB
 +
        Do you want the database to be removed when slapd is purged? No
 +
        Move old database? Yes
 +
        Allow LDAPv2 protocol? No
 +
 
 +
Configure LDAP Server for Webmin
 +
 
 +
Log into webmin with https://172.24.145.25:10000/, go to "Un-used Modules -> LDAP Server"
 +
 
 +
Go to "OpenLDAP Server Configuration", and update the password with "New administration password"
 +
 
 +
Go back and click on "Create Tree", create new DN as below:
 +
 
 +
    For Unix user:
 +
        Distinguished name: dc=Users,dc=localdomain
 +
        Create example object under new DN? Unix user
 +
    For Unix group:
 +
        Distinguished name: dc=Groups,dc=localdomain
 +
        Create example object under new DN? Unix group
 +
 
 +
Now verify the slapd setup by "Apply Configuration", "Stop Server", "Start Server"; also clock on "Browse Database" and should show sometime similar as below:
 +
 
 +
Install nss-pam-ldapd
 +
 
 +
Execute following commands on both machines as LDAP SSO client:
 +
 
 +
aptitude -y install libnet-ldap-perl libpam-ldapd libnss-ldapd ldap-utils nscd nslcd
 +
 
 +
Don't care about the initial question, just feel free to answer them.
 +
 
 +
Also disable nscd or else may generate unexpected result during LDAP lookup debug:
 +
 
 +
update-rc.d-insserv -f nscd remove
 +
/etc/init.d/nscd stop
 +
 
 +
Reconfigure all above packages as below:
 +
 
 +
    dpkg-reconfigure libpam-ldapd
 +
        PAM profiles to enable: Unix authentication, LDAP Authentication
 +
    dpkg-reconfigure libnss-ldapd
 +
        Name services to configure: group, passwd, shadow
 +
    dpkg-reconfigure nslcd
 +
        LDAP server URI: ldap://dev6c1/
 +
        LDAP server search base: dc=localdomain
 +
        LDAP authentication to use: none
 +
        Use StartTLS? No
 +
 
 +
As long as example user and group created in above section, now we can check if LDAP lookup works:
 +
 
 +
getent passwd | grep example
 +
 
 +
Should show similar result as:
 +
 
 +
example:*:9999:9999:Example user:/home/example:/bin/sh
 +
 
 +
Don't forget to test with both machines.
 +
Configure LDAP Client for Webmin
 +
 
 +
Note that Webmin just support libpam-ldap/libnss-ldap officially, but not libpam-ldapd/libnss-ldapd, so the key point for setup LDAP Client at Webmin is to allow all else Webmin module able to access our LDAP server correctly (i.e. also benefit for Virtualmin setup with LDAP authentication backend).
 +
 
 +
Log into webmin with https://172.24.145.25:10000/, go to "Un-used Modules -> LDAP Client"
 +
 
 +
As it complaint configuration file not found (well, for sure, as we are using libpam-ldapd/libnss-ldapd), click on "Module Config" and update as:
 +
 
 +
    LDAP client configuration file: /etc/ldap/ldap.conf
 +
    PAM LDAP configuration file: Same as LDAP client file
 +
    Root LDAP client password files: /etc/ldap/ldap.secret
 +
 
 +
Now it should looks fine. Before configure with Webmin interface let's key in some default value as reference to /etc/ldap/ldap.conf:
 +
 
 +
cat >> /etc/ldap/ldap.conf <<-EOF
 +
host dev6c1
 +
rootbinddn cn=admin,dc=localdomain
 +
base dc=localdomain
 +
nss_base_passwd dc=Users,dc=localdomain
 +
nss_base_shadow dc=Users,dc=localdomain
 +
nss_base_group dc=Groups,dc=localdomain
 +
EOF
 +
 
 +
Access the Webmin interface again, and so click on "LDAP Server Configuration" and double confirm as below:
 +
 
 +
    LDAP server hostnames: dev6c1
 +
    Login for root user: cn=admin,dc=localdomain
 +
    Password for root user: (your_secret_password)
 +
 
 +
Go back and click on "LDAP Search Bases" and double confirm as below:
 +
 
 +
    Global search base: dc=localdomain
 +
    Base for Unix users: dc=Users,dc=localdomain
 +
    Base for Unix password: dc=Users,dc=localdomain
 +
    Base for Unix groups: dc=Users,dc=localdomain
 +
 
 +
Go back and click on "Validate Configuration", if all works it should report as similar as below:
 +
 
 +
    Don't forget to press "Refresh Modules" and check if Webmin able to detech all installed modules correctly.
 +
 
 +
Configure LDAP Users and Groups for Webmin and Usermin
 +
 
 +
Due to changed configuration file path for "LDAP client configuration file" on above section, plus Webmin hardcoded the "auth_ldap=/etc/ldap.conf" in /etc/webmin/ldap-useradmin/config (see http://sourceforge.net/p/webadmin/bugs/3714/?limit=10&page=1#9d30 for complete bug report since 2010), the "LDAP Users and Groups" tab will not show up even pressing "Refresh Modules", and also result as Usermin "Change Password" tab not functioning, too. So let's fix it ;-(
 +
 
 +
First of all update the auth_ldap value accordingly (since no GUI options for changing it):
 +
 
 +
sed -i 's/^auth_ldap=.*$/auth_ldap=\/etc\/ldap\/ldap.conf/g' /etc/webmin/ldap-useradmin/config
 +
 
 +
Next, go to "Webmin -> Usermin Configuration -> Usermin Module Configuration -> Change Password":
 +
 
 +
    Change with: Use PAM or passwd command
 +
 
 +
Now pressing "Refresh Modules" once again, check if following tabs exists correctly:
 +
 
 +
    System -> LDAP Client
 +
    System -> LDAP Users and Groups
 +
    Servers -> LDAP Server
 +
 
 +
Great! Webmin and Usermin should now working together with LDAP correctly ;-)
 +
Create LDAP Users by Webmin
 +
 
 +
Up to this part creating new LDAP user account would be very simple. Just go to "System -> LDAP Users and Groups" and click on "Add a new LDAP user" as show below:
 +
 
 +
Change LDAP Users Password by Usermin
 +
 
 +
Are you looking for a handy way for changing password by your users? It's show time for Usermin!
 +
 
 +
Log into webmin with https://172.24.145.25:20000/ with your user account, go to "Login -> Change Password" and now changing your LDAP user account password with GUI:
 +
 
 +
Next Step?
 +
 
 +
Oh if you are going use Virtualmin then now you can configure it as LDAP backend user storage. Virtualmin will therefore create all new user into your LDAP tree so can populate for any cluster setup usage.
 +
 
 +
If you are going to use NFS or other else cluster file system, using LDAP as SSO can now make other member machine share the same uid/gid with host, therefore Apache2 suexec can operate correctly.

Precise mpi4you

hi,

Upgrade under work, many things changes when moveing from precise to trusty. Same whit notes, those are mixed now. Below precise notes and trusty note's after that. Some trusty update mixed at precise to make everything easyer?

Installation

Cluster Kurrola desing targets: easy to manage ( webmin and LTSP are tested and compared ) , get parallel solvers work ( bind9,dhcp,nfs4 ) giganet whit IP4, stabilize system ( Twin Machine , "4G Cantenna mobile internet Antenna,.." server to work outside world at IPV6 and inside IPV4 / IPV6 (wwdial,hostapd,radvd,shoreline,shoreline6) basic servers ( mysql, postresql, apache2, mediawiki, mythweb, calibre ) and wlan services to workstations

To get parallel software like elmerfem and openfoam to work correctly you need full stack ( name services DNS and routing ) of network service and as learnt at practice at twin machine configuration. Twin machine configuration for DHCP ( both ipv4 and ipv6 ), BIND9 ( master and slave ). BIND9 namaserice is needed to have stable routing even connection to global internet breaks. DHCP is used to networkboot and network address managment. To get IPV6 and IPV4 filtered and routed correctly Shoreline and Shoreline6 are simple tool to configure firewall to Linux kernel. You need device level softaware like wvdial to get 4G modem/router to talk whit server routing and brdegeing software as well hostapd to open wlan services. To manage configuration of servers as well workstations webmin is good tool. To get network working well whit software you need common usernamre as well password base to get communication work between machines and services like NFS4 and rsh-redone.

For post prosessing you need Paraview as well support for 3d mouse. That's possible by building Praview 4.0 from sources whit vrpn and hidapi.

Cluster Kurrola ( MPI4YOU ) base parameters: 

/mpi3 is directory shared via NFS4 to all nodes
/mpi3/B3 Build Script's for version 3
/mpi3/S3 Source Code version 3
/mpi3/C3 Code Verion 3

Each node has Ubuntu 12.04 LTS ( Long Term Suport version, no need to change OS for 7 years )

Connections

NetworkConfiguration.jpg

Installing NetworkManager is simple way to get all right for single machine network. I got big supprise when I understood how complex it come to setup STABILE beawulf parallel network to home, you need to setup all network components.


Ubuntu 12.04 have much automation at protocol stack, it finds devices when connected ([udev]) and most cases setups hardware drivers and creates device like eth and ttyUSB. At Cluster Kurrola Installation NetworkManager is totaly removed due instability and some server software incompatibility issues (calibre,mpich3,rsh-redone). What have to do is to glue kernel IPV4 and IPV6 part's together whit devices and give correct parameter's to devices for operation.

Forcing IPv4 when sending to Gmail

If we want to force postfix to use IPv4 instead IPv6 when sending to Gmail, we need to add a line in the main configuration file of postfix like so 1 2

$ sudo nano /etc/postfix/main.cf transport_maps = hash:/etc/postfix/transport

Let’s create this new file and add a new entry in the transport table. Basically, we fore mail for gmail.com to use smtp-ipv4 (which we have to define later, see below) 1 2

$ sudo nano /etc/postfix/transport gmail.com smtp-ipv4:

Here comes the key part. We create a new rule for our new entry and define to use IPv4 protocol explicitly when this rule applies: 1 2 3

$ sudo nano /etc/postfix/master.cf smtp-ipv4 unix .. .. .. .. smtp 

-o inet_protocols=ipv4

We need to run the postmap command after the change and reload postfix 1 2

$ sudo postmap /etc/postfix/transport $ sudo postfix reload

MYSQL to SSD

Whit TokuDB prevent sw&hw buffering: 

hdparam -W0 /dev/SDD

Mysql run on two SSD at server mpi1 and mpi2, asyncronouse mode mpi2 as master.

Innodb's can not be copyed palce to another, directory name must be same if so you can copy from system to other. So do mysqldump, setup new storage system and re-install databases.


Setup:

/etc/mysql/my.cnf datadir=<sdd dir> 

datadir         = /media/dbs/mysql

/etc/apparmor.d/abstractions/mysql 

  /var/lib/mysql/mysql.sock rw,

I have also found that I needed to UNLOCK TABLES on the slave before starting the slave

In trouble do not forget: 

 mysql_install_db  -  can fix missing files sometimes

HowTo: Repair Ubuntu dpkg status file My Ubuntu 10.04.02 installs starting losing /var/lib/dpkg/status, and you can't update without it... Thanks to capink, but I ended up re-installing anyway so unfortunately losing this file you are near the end of the line.

http://ubuntuforums.org/archive/index.php/t-474587.html Using the script below will generate a new status file in your current directory (usually your home dir). Use this file in place of your status file after backing it up:

  1. !/bin/bash

get_control_info () { for i in /var/lib/apt/lists/*_Packages do sed '/Package: '"$1"'$/,/^$/!d' $i done }

for i in /var/lib/dpkg/info/*.list do package_name=`basename $i | sed 's/.list$//'` get_control_info $package_name >> status-new done

sed -i -e '/^Filename: .*/d' -e '/^MD5sum:/d' -e '/^SHA1:/d' -e '/^SHA256:/d' status-new sed -i '/^Package: /a\Status: install ok installed' status-new

LDAP Single-Sign-On with Webmin on Ubuntu 12.04 HOWTO Submitted by hswong3i on Tue, 2013-01-08 00:01

In order to setup a LAMP cluster we usually need a way to share the master server uid/gid with other else member servers, for whatever NFS shared home directory, or running Apache2 + PHP5 in suexec style. Using LDAP + Webmin can simplify this Single-Sign-On (SSO) need in a handy way.

This HOWTO will guide you though installation of Webmin and OpenLDAP server, then use it as SSO between 2 server with nss-pam-ldapd. First of all let's fouce on making it works, and then enhence it with better security. Server Requirement

In this example let's assume we have 2 servers: dev6c1 and dev6c2, with domain name "localdomain" and IP information as below:

172.24.145.25 dev6c1.localdomain dev6c1 172.24.145.26 dev6c2.localdomain dev6c2

Where dev6c1 will be the master for OpenLDAP, where dev6c2 will be slave that using nss-pam-ldapd as SSO. Install Webmin Manually

Simply execute following commands:

cat >> /etc/apt/sources.list.d/virtualmin.list <<-EOF deb http://download.webmin.com/download/repository sarge contrib deb http://webmin.mirror.somersettechsolutions.co.uk/repository sarge contrib deb http://software.virtualmin.com/gpl/ubuntu/ virtualmin-precise main deb http://software.virtualmin.com/gpl/ubuntu/ virtualmin-universal main EOF

wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add - wget -q http://software.virtualmin.com/lib/RPM-GPG-KEY-virtualmin -O- | sudo apt-key add - wget -q http://software.virtualmin.com/lib/RPM-GPG-KEY-webmin -O- | sudo apt-key add -

aptitude -y install ubuntu-extras-keyring && \ aptitude update && \ aptitude -y full-upgrade && \ tasksel install openssh-server && \ tasksel install server && \ tasksel install mail-server && \ aptitude -y install usermin webmin && \ aptitude update && aptitude -y full-upgrade && aptitude autoclean && aptitude clean

Install OpenLDAP

Execute following commands at dev6c1 as OpenLDAP master:

aptitude -y install slapd libnet-ldap-perl ldap-utils

Don't care about the initial question, just feel free to answer them, as we will now reconfigure it with: 

   dpkg-reconfigure slapd
       Omit OpenLDAP server configuration? No
       DNS domain name: localdomain
       Organization name: localdomain
       Administrator password: (your password)
       Database backend to use: HDB
       Do you want the database to be removed when slapd is purged? No
       Move old database? Yes
       Allow LDAPv2 protocol? No

Configure LDAP Server for Webmin

Log into webmin with https://172.24.145.25:10000/, go to "Un-used Modules -> LDAP Server"

Go to "OpenLDAP Server Configuration", and update the password with "New administration password"

Go back and click on "Create Tree", create new DN as below: 

   For Unix user:
       Distinguished name: dc=Users,dc=localdomain
       Create example object under new DN? Unix user
   For Unix group:
       Distinguished name: dc=Groups,dc=localdomain
       Create example object under new DN? Unix group

Now verify the slapd setup by "Apply Configuration", "Stop Server", "Start Server"; also clock on "Browse Database" and should show sometime similar as below:

Install nss-pam-ldapd

Execute following commands on both machines as LDAP SSO client:

aptitude -y install libnet-ldap-perl libpam-ldapd libnss-ldapd ldap-utils nscd nslcd

Don't care about the initial question, just feel free to answer them.

Also disable nscd or else may generate unexpected result during LDAP lookup debug:

update-rc.d-insserv -f nscd remove /etc/init.d/nscd stop

Reconfigure all above packages as below: 

   dpkg-reconfigure libpam-ldapd
       PAM profiles to enable: Unix authentication, LDAP Authentication
   dpkg-reconfigure libnss-ldapd
       Name services to configure: group, passwd, shadow
   dpkg-reconfigure nslcd
       LDAP server URI: ldap://dev6c1/
       LDAP server search base: dc=localdomain
       LDAP authentication to use: none
       Use StartTLS? No

As long as example user and group created in above section, now we can check if LDAP lookup works:

getent passwd | grep example

Should show similar result as:

example:*:9999:9999:Example user:/home/example:/bin/sh

Don't forget to test with both machines. Configure LDAP Client for Webmin

Note that Webmin just support libpam-ldap/libnss-ldap officially, but not libpam-ldapd/libnss-ldapd, so the key point for setup LDAP Client at Webmin is to allow all else Webmin module able to access our LDAP server correctly (i.e. also benefit for Virtualmin setup with LDAP authentication backend).

Log into webmin with https://172.24.145.25:10000/, go to "Un-used Modules -> LDAP Client"

As it complaint configuration file not found (well, for sure, as we are using libpam-ldapd/libnss-ldapd), click on "Module Config" and update as: 

   LDAP client configuration file: /etc/ldap/ldap.conf
   PAM LDAP configuration file: Same as LDAP client file
   Root LDAP client password files: /etc/ldap/ldap.secret

Now it should looks fine. Before configure with Webmin interface let's key in some default value as reference to /etc/ldap/ldap.conf:

cat >> /etc/ldap/ldap.conf <<-EOF host dev6c1 rootbinddn cn=admin,dc=localdomain base dc=localdomain nss_base_passwd dc=Users,dc=localdomain nss_base_shadow dc=Users,dc=localdomain nss_base_group dc=Groups,dc=localdomain EOF

Access the Webmin interface again, and so click on "LDAP Server Configuration" and double confirm as below: 

   LDAP server hostnames: dev6c1
   Login for root user: cn=admin,dc=localdomain
   Password for root user: (your_secret_password)

Go back and click on "LDAP Search Bases" and double confirm as below: 

   Global search base: dc=localdomain
   Base for Unix users: dc=Users,dc=localdomain
   Base for Unix password: dc=Users,dc=localdomain
   Base for Unix groups: dc=Users,dc=localdomain

Go back and click on "Validate Configuration", if all works it should report as similar as below: 

   Don't forget to press "Refresh Modules" and check if Webmin able to detech all installed modules correctly.

Configure LDAP Users and Groups for Webmin and Usermin

Due to changed configuration file path for "LDAP client configuration file" on above section, plus Webmin hardcoded the "auth_ldap=/etc/ldap.conf" in /etc/webmin/ldap-useradmin/config (see http://sourceforge.net/p/webadmin/bugs/3714/?limit=10&page=1#9d30 for complete bug report since 2010), the "LDAP Users and Groups" tab will not show up even pressing "Refresh Modules", and also result as Usermin "Change Password" tab not functioning, too. So let's fix it ;-(

First of all update the auth_ldap value accordingly (since no GUI options for changing it):

sed -i 's/^auth_ldap=.*$/auth_ldap=\/etc\/ldap\/ldap.conf/g' /etc/webmin/ldap-useradmin/config

Next, go to "Webmin -> Usermin Configuration -> Usermin Module Configuration -> Change Password": 

   Change with: Use PAM or passwd command

Now pressing "Refresh Modules" once again, check if following tabs exists correctly: 

   System -> LDAP Client
   System -> LDAP Users and Groups
   Servers -> LDAP Server

Great! Webmin and Usermin should now working together with LDAP correctly ;-) Create LDAP Users by Webmin

Up to this part creating new LDAP user account would be very simple. Just go to "System -> LDAP Users and Groups" and click on "Add a new LDAP user" as show below:

Change LDAP Users Password by Usermin

Are you looking for a handy way for changing password by your users? It's show time for Usermin!

Log into webmin with https://172.24.145.25:20000/ with your user account, go to "Login -> Change Password" and now changing your LDAP user account password with GUI:

Next Step?

Oh if you are going use Virtualmin then now you can configure it as LDAP backend user storage. Virtualmin will therefore create all new user into your LDAP tree so can populate for any cluster setup usage.

If you are going to use NFS or other else cluster file system, using LDAP as SSO can now make other member machine share the same uid/gid with host, therefore Apache2 suexec can operate correctly. Reference
