Hello Thomas,

we've got a similar configuration up and running as follows:

In a private LAN we have NT- and Win2k- Workstations with
Novell-Netware-Clients, getting their IP-Addresses via DHCP.

On a Suse-7.2-Linux-Box runs Squid, which is the one and only host
of the private LAN allowed to cross the Firewall with http-related

A Netware-Server with LDAP installed, translates NDS-Attributes of
our choice to LDAP.

According to our Policies only some of our users are allowed to surf
the net.

To enable these "privileged" users, we put them into a certain
NDS-group. On the squidhost every 15 Minutes runs a perlscript, which
asks the LDAP Server for a list of IP-Adresses, where members of this
group are currently logged in. This list is than formatted as an
Client-Adress-ACL for squid.

Hence users have to authenticate themselves only once to the
Netware-Server and get enabled or not - independent of their current
IP-Adresses - iff they are members of this privileged group.

If you are interested in details regarding LDAP-attributes, Versions,
above mentioned perlscript (dirty hack!) or so, please feel free to
contact me privately.
Mit freundlichen Grüßen
