Any login can see their own login name, the system logins, and the fixed server roles. To see other logins, requires ALTER ANY LOGIN, or a permission on the login. To see user-defined server roles, requires ALTER ANY SERVER ROLE, or membership in the role.

The visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.

The following query lists the permissions explicitly granted or denied to server principals.

The permissions of fixed server roles do not appear in sys.server_permissions. Therefore, server principals may have additional permissions not listed here.

SELECT pr.principal_id, pr.name, pr.type_desc,   
    pe.state_desc, pe.permission_name   
FROM sys.server_principals AS pr   
JOIN sys.server_permissions AS pe   
    ON pe.grantee_principal_id = pr.principal_id;
