I use the pam_require module from ports for this purpose.
| account sufficient /usr/local/lib/pam_require.so root @mygroup
| account required /usr/local/lib/pam_ldap.so
This allows the user root and members of mygroup to have accounts on the
box. Control falls through to pam_ldap, which is configured with
"pam_check_host_attr yes", which also grants accounts to any user with a
matching "Host: " attribute in their entry.
If I have a machine mybox.example.com, and
uid=ccowart,ou=People,dc=example,dc=com has the attribute:
Then the user ccowart can login to the box without being in mygroup.
Regardless of the host attributes, mygroup members can login.
