OpenLDAP with Kerberos

[zhaoyang mao]

Hi:

recently I tried to configure kerberos under openldap. But it seems a lot of
trouble for me. I don't know how to configure it correctly.
i just want to add some users from openldap using kerberos authentication
method. But it always seem to fail.

Below is my error msg:

LDAP Connection Timeout = 5000 mili-secs
 LDAP Operation Timeout = 15 secs
