Cause
Kerberos authentication failed.
Failed to obtain user
information in LDAP search.
An authentication error
occurred because the user
name contains a space, colon
(:), or quotation mark (").
Authentication timed out
because the server did not
respond.
Solution
1. Kerberos authentication
settings are not correctly
configured.
Make sure the realm name,
KDC (Key Distribution Center)
name, and supporting 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.
The login attribute's search
criteria might not be specified
or the specified search
information is unobtainable.
Make sure the login name
attribute is specified correctly.
Recreate the account if the
account name contains any of
these prohibited characters.
If the account name was
entered incorrectly, enter it
correctly and log in again.
Contact the server or network
administrator.
If the situation does not return to
normal, contact your service
representative.
