Thanks for your reply. But we are ok to use NSS modules to get the uid and gid. We are looking at configuring NSS to use ldap for these details.

I have a patch you could use that implements additional configuration settings to the krb5.conf, provides an optional compile switch for the existing pam_krb5 (--with-ldap), and specifically addresses the UID/GID mapping of remote users by creating a password-less local account (similar to caching mechanisms) for Active Directory/OpenLDAP users.

Of course the necessary POSIX account schema attributes per RFC 2307 ( are required within the directory service you wish to use for the UID, GID, HomeDirectory & DefaultShell account requirements but it should suit your needs.

Here is the patch:
Here is the original pam_krb5 provided by RedHat:
Here is additional documentation on the project to help with patching, compiling, installing and configuring (this might be slightly outdated):

Hope that helps some.

You will not. PAM does only authenticate an user for you,
nothing more. What you mean is getpwnam() and similar functions
handled by NSS modules.
