The SVN3000 was configured for certificate anonymous authentication and VPNDB authorization. After a user was authenticated, the authentication page was redisplayed without any error messages.
Debug the SSL error. There is no output, which indicates that the certificate authentication process is normal.
Debug the VPNDB error. A message is displayed stating that user A does not exist.
Add user A and set the password to any values. The authentication succeeds.
Anomalies occur during authentication or authorization.
A password is required for creating a user in the VPNDB. The password is useless in certificate anonymous authentication mode, because authorization is based on the user name. Therefore, the password can be set to any values.
