tac_plus AD integration with PAM

[Yu Wang]

Try use pam_ldap for account (authorize) part. You will need to create 
pam_ldap.conf or ldap.conf, depends on your server OS, to query a user's 
attribute (uid).

Your pam.d/tac_plus account part would look like:

account     required      pam_unix.so broken_shadow
account     sufficient    pam_localuser.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore] pam_ldap.so 
<------
account     required      pam_permit.so
