It is very possible that you came across either one of the flavors of the two error messages shown below: 2016-07-08 23:53:59.63 Logon Error: 18456, Severity: 14, State: 11.2016-07-08

There are two permissions that come into play while performing these authorization checks: - Does the login have the SERVER class permission named CONNECT SQL for this server instance? - Does the login have the ENDPOINT class permission named CONNECT for the specific endpoint on which the client application established the connection?
