When network security is not enabled, Replication Server logs in to remote servers as one of several possible users, depending on the task to be performed. When network-based security is enabled with unified login, Replication Server must log in to remote servers as the principal user. The principal user credential is the only credential Replication Server has to log in to other processes when network security is active.
When Replication Server logs in to another Replication Server or a data server, the principal user name contained in the credential is mapped to the server name space and a secure connection is established.
Make sure that principal user names are unique. Replication
Server cannot log in to another server of the same name.
Replication Server executes the set proxy command in the remote server (as the principal user) and switches to the appropriate user for the current task.
