[ic] question about the 'login' feature

[interchange-users@interchange.redhat.com (chad townsend)]

i'm using interchange 4.8.2 with the foundation template and i need to add a tiny bit of
functionality into the login feature.  when someone logs in i not only need it to check to make sure
the user and pass are correct i need to perform one more check, which will be a simple data.table
lookup.

something like, if (user eq $user and pass = $pass and check = $check) { pass; } else { fail; }

i'm not sure exactly the best approach i should take to accomplish this.  any insight or direction
is most appreciated.

thanks,
