How to: Manage Logins in the Publication Access List (SQL Server Management Studio)
You use the publication access list (PAL) on the Publication Access List page of the Publication Properties - <Publication> dialog box to manage logins. For more information about how to access this dialog box, see How to: View and Modify Publication and Article Properties (SQL Server Management Studio).
You must associate the SQL Server login with a database user in the publication database before adding the login to the PAL.
To manage logins in the PAL
On the Publication Access List page of the Publication Properties - <Publication> dialog box, use the Add, Remove, and Remove All buttons to add and remove logins and groups from the PAL. Do not remove distributor_admin from the PAL. This account is used by replication.
If a remote Distributor is used, accounts in the PAL must be available at both the Publisher and the Distributor. The account must be either a domain account or a local account that is defined at both servers. The passwords that are associated with both logins must be the same.
