LDAP Authentication fails for some users after importing group from LDAP.
Some users from LDAP group failed to authenticate when running test on the SonicWall Security Appliance while other users from the same LDAP group can authenticate successfully.
Step 1: Navigate to Users | Settings Step 2: Uncheck box for 'Case-sensitive user names' Step 3: Click 'Accept'. Users now should be able to authenticate.
In a windows domain case sensitivity is not an issue when entering credentials. When a Domain user attempts to enter his credentials with "Case-sensitive user names" enabled on the appliance and if the user's credentials on the LDAP server are in a different case then the authentication fails on the appliance.
