In this case, the credentials will not have been used, and may also be invalid, but the server never had a chance to find out.

Invalid user/password

Incorrect user/password information will lead to the initial connection failing with an MQ code of 2035 (MQRC_NOT_AUTHORIZED):

Invalid setdbparms credential name

If the mqsisetdbparms alias referenced by the MQEndpoint policy does not exist (as opposed to containing incorrect user/pw information), the server will attempt to start and then fail with a "broken connection" error as follows:
