the problem is that we need to synchronize firewall rules in linux servers depending who is logged in in which machine.
for example:
when userA logs in pcB the script in the PDC runs (with the arguments of userA and pcB) and remotely executes in a linux firewall some commands that adapt the firewall so that the firewall allows traffic from pcB according to rules set for userA. Hope I wasn't too confusing.
I know with ISA server this is somewhat easy and automatic, but our network is very deep built under linux, and we don't wan't to change that, but this would be a great functionality.
