Bordermanager 3.9 on Netware 6.5 SP8

Configured VPN server and Client to Site service.

When a client attempts to connect, the following error is displayed: "Authentication gateway failed to verify entered parameters." "A general error was reported by the authentication gateway."

The log shows the following:

A connection was opened for a VPN client at address xx.xx.xx.x.
2011-07-05 09:34:56 VPN client user name at address xx.xx.xx.x is xxxxxxxxxxxxx.
2011-07-05 09:34:56 AuthClient # 0 (xx.xx.xx.x): GetCH: Alloc for user name failed.
2011-07-05 09:34:58 Connection closed for the VPN client at address xx.xx.xx.x.

Any help would be appreciated.

Thank You,
Jason Rothwell
