Analysis
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 format userid@isp-name, 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.
Solution
To resolve the problem:
1. Check 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
