cgi authentication software

[ken klippel]

Is anyone aware of a freeware/shareware cgi script which can be used to 
authenticate users access to specific web pages. I have some pages which 
must be limited to certain staff groups and I would like to make a little 
Username - password page to restrict access.

This seems such a straightforward process I cant work out why I cant find 
anything on the big software/cgi sites. I presume I am missing something 
obvious. I have tried the Selena Sol authentication software and it 
doesnt quite do what I want.

Many thanks
