sudo: Can't contact LDAP server with SSL and PAM
The LDAP server is on Centos5.8 and one of client nodes is Centos 6.3. I configured the client node contact LDAP server successfully and the account can be authenticated, but when I type command 'sudo -s' on the client, the system reported : sudo: ldap_sasl_bind_s(): Can't contact LDAP server.
connection between client and server is via ssl through port 636, which I have configured in /etc/nslcd.conf.
I created a sudo group in LDAP server and avoid using local sudo configuration.
I am able to ssh client node using LDAP user, but sudoers cannot be verified, keep asking for password.
