Uwagi

Permissions at the server scope can be denied only when the current database is master.

Information about availability groups is visible in the sys.availability_groups (Transact-SQL) catalog view. Information about server permissions is visible in the sys.server_permissions catalog view, and information about server principals is visible in the sys.server_principals catalog view.

An availability group is a server-level securable. The most specific and limited permissions that can be denied on an availability group are listed in the following table, together with the more general permissions that include them by implication.
