cluster setup for HA and security
Posted on 2014-04-17
I am new to SQL Server clusters for HA, but from a security angle, say for example you have 10 SQL Servers in the cluster, and Server 1 dies, do Server 2 takes on the databases in Server 1 - how are the logins in Server 1 carried over so users can still login and access their databases? Or do you have to clone all accounts on all servers so they can still login to any server. This seems hugely unsecure to me, as users who need access to a DB on server 1 will have no requirement to access DB's on other servers in the node. So how does it work? Please keep answers basic for someone new to this.
