Re: [FW-1] VPN Authentification



Amaury,

We experienced this same dilema with FW-1.   It was about 4 years ago,
however, so I don't know if the same
problem still exists.

We ended up going with a Nortel Contivity solution for client VPN services.
It allows you to set up lots of customized access-lists (based on groups) on
the Contivity gateway.   You can authenticate users in one of 2 ways (native
LDAP   or   Radius).   Either way, based on a group the user belongs to, the
groupname gets passed back to the VPN box, and it uses the access-list
define for that groupname to restrict what a user can do.    In the case of
radius, the groupname is passed back as a value of the generic radius Class
attribute.  The form it needs to take is "ou=groupname".

This may not help your FW-1 situation, but it might at least be comforting
to know that others have experienced this same frustration.

Feel free to send me an email if you want more information.
