RE: Hoe to get uid,gid through PAM



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 (http://www.ietf.org/rfc/rfc2307.txt) 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: https://github.com/jas-/pam_krb5-ldap
Here is the original pam_krb5 provided by RedHat: https://fedorahosted.org/pam_krb5/
Here is additional documentation on the project to help with patching, compiling, installing and configuring (this might be slightly outdated): https://help.ubuntu.com/community/Alternate_Pam_Krb5LDAP_Authentication

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.
