Problem with WebVPN and AD authentication

[jbeining]

I have an ASA5510 and a VPN 3005

I want my users to connect via WebVPN and authenticate against the AD. This works very well, until my users are member of more than 9 AD groups. They just get rejected with the "unspecified reason"

Anyone has or knows about this problem?

Both IPSec and WebVPN on the Cisco VPN 3000 Concentrator can authenticate against AD, But iam not sure the number of AD groups.
