Looking to fine tune Cisco IPSec client RA-VPN authentication on our ASA-5510. Currently using NT Domain authentication. It's been working fine for quite a while but is too broad a brush. It authenticates anyone who is in the domain. We need to only authenticate folks who are in a specific AD remote access security group. I'm testing LDAP but am getting the same results. I can get it to authenticate based on overall domain membership but can't seem to figure out how to check group membership.
We've updated to ASA 8.2(1) and ASDM 6.2(1). It seems to have more LDAP functionality but I'm not an LDAP expert. I've posted an image of the LDAP server dialog from the ASDM. I originally tried putting the Group DN in the Base DN field but kept getting a "can't find user" error when testing. I also tried adding the group info in the "LDAP parameters for group search" field at the bottom. But it doesn't seem to be looking there. Note that the current value is the Group Base DN only. I also tried putting "memberOf=" in front of that. Still no luck. The values shown in the image work for simple domain membership. I'm just stumped with how to kick off the second step to check group membership.
Anyone have a sample config floating around?
