Error Code Cause Solution
L0406-204 Kerberos authentication failed. 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.
L0409-000 Authentication timed out because
the server did not respond.
Contact the server or network
administrator.
If the situation does not return to
normal, contact your service
representative.
L0511-000 The authentication server login name
is the same as a user name already
registered on the machine. (Names
are distinguished by the unique
attribute specified in the LDAP
authentication settings.)
1. Delete the old, duplicated name
or change the login name.
2. If the authentication server has just
been changed, delete the old name
on the server.
L0607-001 An authentication error occurred
because the Address Book is being
used at another location.
Wait a few minutes and then try
again.
L606-004 Authentication failed because the
user name contains language that
cannot be used by general users.
Do not use "other", "admin",
"supervisor" or "HIDE*" in general
user accounts.
