We have one user, who is getting authentication errors when trying to connect to our Cisco 3005 Concentrator from a Windows XP SP2 client, using Cisco VPN client 4.8.02. The VPN group he belongs to authenticates against our Windows 2003 AD domain. All of our other VPN 3005 users are authenticating fine.
This one user happens to have an unusually long login name. Could the length of his user name be part of why the authentication is failing?
