One more question.If you do not have access to server B beyond db_owner in the database,
how do you ensure that the logins (server principals) are synced?
As db_owner, you cannot do anything except ask someone else to sort it out (e.g. someone with sysadmin or securityadmin priveleges).
You would already need to be doing that - mirroring does not do anything about logins. Logins are at the server level, database mirroring is at the database level.
