Please Help With mod_auth_external

Hi

I am using mod_auth_external-2.1.16 for password authentication, with
an external script, it works fine for password authentication, I world
like to start using it also for groups authentication, but I don't
rely see how I could find out which group is in my .htaccess file.

I will explain my self
I am trying to use mod auth for Apache NIS group and password
authentication, to require users supply logins and passwords before
accessing pages in some directories.
1) I would like to check if the password given is correct for a user
2) I would like to check if the user given is in the group that I
entered in the .htaccess file (which my script will check if the user
given and the group allowed in .htaccess file match the NIS user group
entry)

For password authentication it works fine, look my example below, but
for group authentication not, I don't know how I could find out what
groups are in the .htaccess file to be able to match it up with the my
NIS groups

I know that mod_auth_external gives you back the user as USER,
password as PASS, and group as GROUP, for user and password its simple
because this is user entry's but for groups this is something in the
..htaccess file, for GROUP variable what to what group is it set, not
the group that is in my .htaccess file

Any help is greatly appreciate
Thanks
