[!INCLUDEssNoVersion] logins and server roles are server-level securables. The most specific and limited permissions that can be granted on a [!INCLUDEssNoVersion] login or server role are listed in the following table, together with the more general permissions that include them by implication.

SQL Server login or server role permission	Implied by SQL Server login or server role permission	Implied by server permission
CONTROL	CONTROL	CONTROL SERVER
IMPERSONATE	CONTROL	CONTROL SERVER
VIEW DEFINITION	CONTROL	VIEW ANY DEFINITION
ALTER	CONTROL	ALTER ANY LOGIN ALTER ANY SERVER ROLE

Permissions

For logins, requires CONTROL permission on the login or ALTER ANY LOGIN permission on the server.

For server roles, requires CONTROL permission on the server role or ALTER ANY SERVER ROLE permission on the server.

Examples

A. Granting IMPERSONATE permission on a login

The following example grants IMPERSONATE permission on the [!INCLUDEssNoVersion] login WanidaBenshoof to a [!INCLUDEssNoVersion] login created from the Windows user AdvWorks\YoonM.

USE master;  
GRANT IMPERSONATE ON LOGIN::WanidaBenshoof to [AdvWorks\YoonM];  
GO  

B. Granting VIEW DEFINITION permission with GRANT OPTION

The following example grants VIEW DEFINITION on the [!INCLUDEssNoVersion] login EricKurjan to the [!INCLUDEssNoVersion] login RMeyyappan with GRANT OPTION.

USE master;  
GRANT VIEW DEFINITION ON LOGIN::EricKurjan TO RMeyyappan   
    WITH GRANT OPTION;
