tac_plus AD integration with PAM

[Donato Rivera]

Yu,

Thank you for the contribution and help.

I have tried changing these settings with no change.  I am not sure if my ldap.conf is correct or if I need to link it to another file.  currently it sits in this dir  /etc/openldap/ldap.conf.

I used the krb5.conf file going of the instructions found on the shrubbery.net forums which recommened using krb5 and not ldap for Active Directory integration with tac_plus.

Going from a paid application to this solution has had challenges but this is really the last hurdle to cross so I am open to trying any configuration at this point.

I will keep try variations of your suggestion and let you know the outcome.

Once again thank you for the post and if you have any other suggestions please pass them along.

Danny

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
