We are working on a migration, a few db's a night for the next week. Part of the migration requires that we shutoff access to the database. This is a 3rd party application and, in their infinite wisdom, they created a single login that maps to a user in each database.
As such, I cannot disable the login. Is there a way to disable the user or unmap it from the login?
Note, I am not able to take the DB offline, rename it, etc, which complicates things more.
