注释

To get Login object properties, users can be a member of the public fixed server role.

To set Login object properties, users must have ALTER ANY LOGIN permissions on the server or be a member of the sysadmin fixed server role.

To create or drop a login, users must have ALTER ANY LOGIN permissions on the server or be a member of the sysadmin fixed server role.

To grant, deny, or revoke permission on the login to other users, users must have CONTROL permissions on the logon or be a member of the sysadmin or securityadmin fixed server roles.

To set the password on a login without providing an old password, users must be a member of the sysadmin fixed server role.
