LDAP is not authenticating users.
 

i am trying to do ldap authentication using PAM in Centos.
I have disabled the anonymous access in LDAP [by default anonymous access is enabled] and configured binddn and bindpw in /etc/ldap.conf file leads PAM to bind with LDAP.

ldapsearch is showing the users and binding with the dn which i have created. i have verified by executing the ldapsearch utility.

Sometimes it is happening and after some time it is not happening. I have not changed anything in the default code base.

Could anybody help me in this situation.

Thanks

Have you run the Authentication Configuration Tool (system-config-authentication) and select Enable LDAP Support under the the Authentication tab ?

yes i have executed the authconfig tool and enabled LDAP authentication. Problem is sometimes it is authenticating sometimes not. behaviour is strange...

Thanks

When user is not able to log-in,have you checked the LDAP server is still running?
Paste your ldap log file contents here.
