[erlang-questions] mod_auth usage?

[Michael L Martin]

Hello all,

I'm trying to get my head around mod_auth in httpd. The doc for 
add_user/2 says that Password, UserdData, Port, and Dir are required 
options, but there is no description of what these are or should be 
(well, Password is pretty obvious).

Can someone out there shine some light on this subject?

Thanks,
Michael
