How do I configure Ezeelogin to authenticate using Windows_AD(Pam-LDAP) in CentOS?
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.
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
Step 2: Add the details of LDAP configurations & enable Windows Active Directory.
Multiple URIs or a list of URIs can be specified in the format:
- ldaps://host.com:636/ ldaps://host.com:636/
(Only the protocol, hostname, and port fields are allowed.)
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:
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
Login to Ezeelogin ssh server to configure pam-LDAP.
Step 1: Install pam-LDAP module by the following command
Step 2: Enter the command to auto-configure
Step 3: Select use LDAP & use LDAP authentication
Step 4: Add binddn,bind password & Active Directory Mappings to /etc/nslcd.conf
Note: If you are using LDAPS, then change SSL to YES
Step 5: Enable auto-create home directory on login by the following command
Step 6: Restart nslcd & nscd service
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
Login: jake Name: 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"
