Use the system procedure sp_addexternlogin to assign an alternate login name and password to be used when communicating with a remote server. This step is optional. The syntax for sp_addexternlogin is:
sp_addexternlogin remote_server, login_name, remote_name [, remote_password]
where:
remote_server is the name of the remote server. The remote_server must be known to the local server by an entry in the master.dbo.sysservers table.
login_name is an account known to the local server. login_name must be represented by an entry in the master.dbo.syslogins table. The “sa” account, the “sso” account, and the login_name account are the only users authorized to modify remote access for a given local user.
remote_name is an account known to the remote_server and must be a valid account on the node where the remote_server runs. This is the account used for logging into the remote_server.
remote_password is the password for remote_name.
sp_addexternlogin FRED, sa, system, sys_pass
Allows the local server to gain access to remote server FRED using the remote name “system” and the remote password “sys_pass” on behalf of user “sa”.
sp_addexternlogin OMNI1012, bobj, jordan, hitchpost
Tells the local server that when the login name “bobj” logs in, access to the remote server OMNI1012 is by the remote name “jordan” and the remote password “hitchpost”. Only the “bobj” account, the “sa” account, and the “sso” account have the authority to add or modify a remote login for the login name “bobj”.
