If you want to restrict access to a service on a PAM enabled OS, I think
it is better to let pam_ldap auth the password and restrict groups, etc...
using the PAM module intended for that purpose, pam_listfile
auth required /lib/security/pam_listfile.so onerr=fail
item=group sense=allow file=/etc/security/login_limit_list.conf
auth required /lib/security/pam_securetty.so
auth required /lib/security/pam_stack.so service=system-auth
where /etc/security/login_limit_list.conf looks something like -
Just a list of groups.
