PAM configuration: Kerberos authentication and NIS authorization problem
Hi,
I've configured two linux boxes to authenticate against Windows Active Directory using Kerberos while retrieving authorization data (uids, gids ,,,)from NIS.
The problem I ran into with my PAM configuration is that all authentication attempts succeed in order.i.e. if someone tried his NIS credentials he will be granted access!!
What I want is this: Kerberos authentication is tried first; if it fails, local files authentication ONLY is tried.
here's my PAM configuration from system-auth pam configuration file which is included by all systems pam-aware services:
The issue here: I think the pam_unix module somehow contacts NIS for authentication if Kerberos fails. But, I had updated my sswitch.conf to look like:
I thought the pam_unix.so module references this file to see where to look up passwords.
Please note that I can't remove nis form passwd and group sections because this is needed to get authorization (uid,gid) data from NIS.
The point is, above nsswitch.conf didn't resolve the issue, users are still able to log in using their NIS credentials!

The company I work for is trying to implement Sudoers.LDAP to centralize their sudoers infrastructure so the access management team and compliance teams don't have to run ragged over all of our servers.
