Resolution for SonicOS 6.5

This release includes significant user interface changes and many new features that are different from the SonicOS 6.2 and earlier firmware. The below resolution is for customers using SonicOS 6.5 firmware.

When this error occurs the following log message is generated. From the log message it is evident that this is an LDAP Bind error. When integrating SonicWall with an LDAP server, the user entered under Login user name under Manage | Users | Settings | Configure LDAP | Edit your LDAP server | Login/Bind Tab makes a Bind request. This request could fail if the username, password or the directory entered under User tree for login to server is incorrect.

Check the following to correct this issue

1. That the Login user name on the Manage | Users | Settings | Configure LDAP | Edit your LDAP server | Login/Bind Tab  (if Give login name/location in tree is selected) is the display name and not the username.
   
   

   EXAMPLE: John Doe is a display name and jdoe is the username. and That the above user is in the directory entered under User tree for login to server. This is normally the Users directory.
   

2. If Give bind distinguished name is selected under Manage | Users | Settings | Configure LDAP | Edit your LDAP server | Login/Bind Tab, make sure it is correct. For example, this is the DN of an administrator in the Users directory.
   CN=Administrator,CN=Users,DC=sonic,DC=lab
   
   
3. That the password entered is correct.
   

   NOTE: The user to bind to the LDAP server could be a normal domain user and need not be an administrator.
