The Ingres PAM Configuration File (for Kerberos)
The contents of the Ingres PAM file are very similar to the LDAP configuration, except Kerberos libraries are substituted for the LDAP libraries. The following configuration will work equally well for Active Directory and Kerberos KDS servers:
auth sufficient pam_krb5.so
auth sufficient pam_nologin.so
account sufficient pam_krb5.so
Note:  The krb5.conf and ingres files are owned by root, but must be world-readable. Execute chmod 644 on these files to ensure they have the correct permissions.
