SQL 2008 R2 Implementing database mirroring. Mirroring endopoints created on both partner servers (principal and mirror) and on the witness.
Was planning to GRANT CONNECT permissions on the mirroring endpoints to the domain account under which the database servers (partners and witness) are running.
Question: Why do we need to create a database server login for this domain account on each database server? The domain account should already have full priviliges on the database servers.
