Integration of Open-LDAP (PAM-LDAP) in CentOS

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

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

1. Login to Web-GUI > Settings > LDAP

Add the details of LDAP configurations

2. Under Settings > General > Authentication > change webpanel authentication to LDAP & Enable External SSH Auth

3. Select the LDAP users and import them to Ezeelogin

You can confirm the imported LDAP users were listed in the Users

Now you can login to Ezeelogin GUI with LDAP user.

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.

Let's configure PAM_LDAP Authentication for SSH

1. Install pam-LDAP module by the following command

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

2. Enter the command to auto-configure

root@gateway ~]# authconfig-tui

Select use LDAP & use LDAP authentication

3. Add Binddn & bind password to /etc/nslcd.conf

root@gateway ~]# vi /etc/nslcd.conf

binddn cn=admin,dc=eztest,dc=net

bindpw chaSD@#234JH56hj^7

map passwd loginShell "/usr/local/bin/ezsh"

And add bindn and bind password to the file

4. Enable autocreate home directory on login by the following command

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

5. Restart nslcd & nscd service

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

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

Now run the id/finger command and see whether you are able to get LDAP user details

[root@jumpserver ~]# finger jake

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

Last login Wed Jun 13 05:02 (EDT) on pts/1 from 10.1.1.13

No mail.

No Plan.

[root@jumpserver ~]# id jake

uid=1001(jake) gid=20001(domain users) groups=1547600513(domain users)

Run an ldapsearch to ensure that results are correctly fetched from the LDAP server.

ldapsearch -v -x -H ldap://10.11.1.164 -b "cn=jake j,cn=Users,dc=ad2016,dc=admod,dc=net" -D "cn=administrator,dc=ad2016,dc=admod,dc=net" -w redhat
