8. Troubleshooting
• If a user enters sAMAccountName as the login user name, ldap_bind fails in a parent/subdomain
environment. Use UserPrincipleName for the login name instead.
W0406-003
An authentication error occurred because the user name contains a space, colon (:), or quotation mark
(").
• 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 on again.
W0406-101
Authentication cannot be completed because of the high number of authentication attempts.
• Wait a few minutes and then try again.
• If the situation does not return to normal, make sure that an authentication attack is not occurring.
• Notify the administrator of the screen message by e-mail, and check the system log for signs of an
authentication attack.
W0406-107 : Case 1
The UserPrincipleName (user@domainname.xxx.com) form is being used for the login user name.
• 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.
W0406-107 : Case 2
Current settings do not allow group retrieval.
• Make sure the user group's group scope is set to "Global Group" and the group type is set to
"Security" in group properties.
• Make sure the account has been added to user group.
• Make sure the user group name registered on the machine and the group name on the DC (domain
controller) are exactly the same. The DC is case sensitive.
• Make sure that "Use Auth. Info at Login" has been specified in "Auth. Info" in the user account
registered on the machine.
• If there is more than one DC, make sure that a confidential relationship has been configured
between each DC.
W0406-107 : Case 3
The domain name cannot be resolved.
• Make sure that DNS/WINS is specified in the domain name in "Interface Settings".
W0406-107 : Case 4
Cannot connect to the authentication server.
