Is there a way to disable or lock the group “account” so the role/privilege cannot be used or does not get used until it is needed for maintenance as a security requirement?
In the Users and groups, one can give set passwords for these” groups” not just the “users” so they must be technically accounts that can be used to elevate privileges.
I see owners to tables for example:
DBA (this is the only one that is an actual “user”)
SYS (this shows it is a group(role))
Dbo (this shows it is a group(role))
Rs_systablgroup (this shows it is a group(role))
