Integration of WINDOWS-AD (PAM-LDAP) in CentOS 7/6

Overview: This article details the steps to integrate WINDOWS-AD (PAM-LDAP) in CentOS 7/6. It includes PHP-LDAP installation, LDAP configuration via web GUI, and setting up PAM_LDAP for SSH access, ensuring seamless LDAP user import and configuration verification.

Note: Make sure that the PHP-LDAP extension is installed on the server

root@gateway:~# yum install php-ldap openldap openldap-clients; apachectl restart

Step 1: Login to Web-GUI -> open settings -> Ldap

How to find base DN and bind RDN

Step 2: Add the details of LDAP configurations & enable Windows Active Directory

Step 3: Under Settings -> General Settings -> Authentication -> Change web panel authentication to LDAP & enable External SSH Auth

Step 4: Select the LDAP users and import them to Ezeelogin

Step 5: You can confirm the imported LDAP users were listed in the users tab. After the successful import you can login as the LDAP user.

Note: When importing an LDAP user, they will be assigned to the default group or the mapped user group. After the import, if we change the LDAP user to another user group, we will receive a note saying "Group Mismatch." This is not an error.

Note:

After importing the users to Ezeelogin, log in with the user and set up security code for the user under Account > Password > New Security Code.

Step 6: Make sure that UNIX ATTRIBUTES are enabled on WINDOWS(2003,2008,2012) SERVER

Note:

You do not need to install Unix attributes on windows 10, windows 2012 and windows 2016 server OS

Step 7: Login to Windows server, open Command Prompt, and enter the following command:

 Dism.exe/online/enable-feature /featurename:nis  /all 

Reboot the server to complete the installation

Win 2008 Unix Attributes

Window 2016 AD for a user . Note that the attributes such as uidNumber = 10001 , gidNumber = 12001 , unixHomeDirectory = /home/jake , loginShell=/usr/local/bin/ezsh are set.

Note: For the Unix Attributes uidNumber, gidNumber, and login shell to be visible, make sure to click on the Filter button and select ONLY " Show Only Writable Attributes" as shown below.

Let's configure PAM_LDAP Authentication for SSH

Step 1: Install pam-LDAP module by the following command

root@gateway:~# yum install nss-pam-ldapd nscd

Step 2: Enter the command to auto-configure

root@gateway:~# authconfig-tui

Step 3: Select use LDAP & use LDAP authentication

Step 4: Add binddn,bind password & Active Directory Mappings to /etc/nslcd.conf

root@gateway:~# vi /etc/nslcd.conf  uri ldap://10.11.1.231 
 ldap_version 3 
 base cn=users,dc=admod,dc=net 
 binddn cn=Administrator,cn=Users,dc=admod,dc=net 
 bindpw admod_2012  
 filter passwd (objectClass=User) 
 map passwd uid sAMAccountName 
 map passwd homeDirectory unixHomeDirectory 
 map passwd loginShell  "/usr/local/bin/ezsh" 
 map passwd gidNumber   "100" 
 
 ssl no 
 tls_cacertdir /etc/openldap/cacerts 

Note: If you are using LDAPS, then change SSL to YES

Step 5: Enable auto-create home directory on login by the following command

root@gateway:~# authconfig --enablemkhomedir --update

Step 6: Restart nslcd & nscd service

root@gateway:~# service nslcd restart && service nscd restart   

Note: Ensure the login shell of LDAP user is /usr/local/bin/ezsh

Step 7: Now run the id/finger command and see whether you are able to get AD user details

root@gateway:~# finger jake

Directory: /home/jake Shell: /usr/local/bin/ezsh

Last login Tue Jul 3 12:23 (IST) on pts/2 from 10.11.1.189

No mail.

No Plan.

root@gateway:~# id jake

uid=10001(jake) gid=12000 groups=12000

Note: Run a ldapsearch to check the values returned from your AD server as follows. This is used for troubleshooting.

root@gateway:~# ldapsearch -x -LLL -E pr=200/noprompt -h 10.11.1.164 -D "[email protected]" -w admod_2016 -b "cn=jake,cn=users,dc=ad2016,dc=admod,dc=net"
