One of our DBAs recently left, and when I was removing there login I found they had explicitly granted a connect on the availability group's endpoint to it's login.
The login itself is a sysadmin, so everything I can find online seems to say that it should automatically have connect permissions to all endpoints.
Is there any reason that this would need an explicate grant? And if not, will just revoking the permission cause any issues? I am afraid that just revoking the permission will bring down the availabity group even though I cannot find a reason it exists.
Thanks,
Jamie
