Error Code
W0406-104 5. Kerberos authentication failed.
W0400-105 1. The UserPrincipleName
(user@domainname.xxx.com) form
is being used for the login user
name.
Cause
1. Kerberos authentication settings
are not correctly configured.
Make sure the realm name, KDC
(Key Distribution Center) name and
corresponding domain name are
specified correctly.
2. The KDC and machine timing do
not match.
Authentication will fail if the
difference between the KDC and
machine timing is more than 5
minutes. Make sure the timing
matches.
3. Kerberos authentication will fail if
the realm name is specified in lower-
case letters. Make sure the realm
name is specified in capital letters.
4. Kerberos authentication will fail if
automatic retrieval for KDC fails.
Ask your service representative to
make sure the KDC retrieval settings
are set to "automatic retrieval".
If automatic retrieval is not
functioning properly, switch to
manual retrieval.
The user group cannot be obtained
if the UserPrincipleName
(user@domainname.xxx.com) form
is used.
Use "sAMAccountName(user)" to
log in, because this account allows
you to obtain the user group.
If Authentication Fails
