When authenticating using the DN format, login attributes do not need to be registered.
The method for selecting the user name depends on the server environment. Check the server
environment and enter the user name accordingly.
16. Press [Change] for "Unique Attribute".
17. Enter the unique attribute and then press [OK].
Specify unique attribute on the machine to match the user information in the LDAP server with that in
the machine. By doing this, if the unique attribute of a user registered in the LDAP server matches
that of a user registered in the machine, the two instances are treated as referring to the same user.
You can enter an attribute such as "serialNumber" or "uid". Additionally, you can enter "cn" or
"employeeNumber", provided it is unique. If you do not specify the unique attribute, an account
with the same user information but with a different login user name will be created in the machine.
18. Press [OK].
