samba automount home directory with RH 6.5 but without PAM_MOUNT

hello,
RH 6.5 x86_64 doesn't include the PAM_MOUNT package then it's not possible to automount a shared home directory (CIFS share) when users AD get connected on our servers.

how to replace the pam_mount feature with RED HAT 6.5 ?

thank you
