Nortel Secure Network Access Switch 4050 User Guide

 

The default Boot user password cannot be changed, and can therefore never really 
be lost. If you have forgotten the Boot user password, see 

The reason the Boot user password cannot be changed is that, if you lost both the 
Administrator password and the Boot user password, the Nortel SNAS 4050 
would be rendered completely inaccessible to all users except the Operator, who 
does not have rights to make configuration changes.

The fact that the Boot user password cannot be changed is not a security concern. 
The Boot user can only access the Nortel SNAS 4050 with a console connection 
using a serial cable, and it is assumed that the Nortel SNAS 4050 device is set up 
in a server room with restricted access.

The following are common reasons why a user may have difficulty authenticating 
to the Nortel SNAS 4050 domain or why a client connection cannot be 
established.

•

The user name or password is wrong.

•

The configured authentication server cannot be reached.

•

The group name retrieved from the authentication server does not exist on the 
Nortel SNAS 4050.

Use the 

 command to trace the different steps involved in a 

specific process, such as authorization.
