LDAP authentication failure

User authentication fails.

Possible reasons include:

• A communication failure exists between the NAS and the LDAP server.

• The LDAP server IP address or port number configured on the NAS is not correct.

• The username is not in the userid@isp-name format, or the ISP domain is not correctly configured on the NAS.

• The user is not configured on the LDAP server.

• The password entered by the user is incorrect.

• The administrator DN or password is not configured.

• Some user attributes (for example, the username attribute) configured on the NAS are not consistent with those configured on the server.

• No user search base DN is specified for the LDAP scheme.

To resolve the problem:

1. Verify the following items:

   • The NAS and the LDAP server can ping each other.

   • The IP address and port number of the LDAP server configured on the NAS match those of the server.

   • The username is in the correct format and the ISP domain for the user authentication is correctly configured on the NAS.

   • The user is configured on the LDAP server.

   • The correct password is entered.

   • The administrator DN and the administrator password are correctly configured.

   • The user attributes (for example, the username attribute) configured on the NAS are consistent with those configured on the LDAP server.

   • The user search base DN for authentication is specified.
