Specify each user by the user’s UNIX name. Separate the names in the list using a comma.

Alternatively, you can using the file: keyword to specify a separate file that contains UNIX user names.
You can put a UNIX user name in each single line, and be sure to run the adreload command after modifying the file to have the changes take effect.
The default value for this parameter is empty.
