TOPIC: create a login ,who can add other logins to databases (securityadmin server role)
*/
USE MASTER
GO
Create login securityTestLogin with password = '@@somepassword123'
-----add this to server , this is server level security role -------
EXEC master..sp_addsrvrolemember @loginame = N'securityTestLogin', @rolename = N'securityadmin'
--- first this login should be a user in database where we want to give other users access
USE HTDBA
GO
Create user securityTestLogin for login securityTestLogin
EXEC sp_addrolemember N'db_accessadmin', N'securityTestLogin'
-- depends on your requriemtnt you might also want this permission too
--EXEC sp_addrolemember N'db_securityadmin', N'securityTestLogin'
GO
------ Now we think about adding other users to different database roles -------------
/*
There is one gottcha , db_securityadmin role cannot add users to the fixed database roles ,only
db_owner can perform this action , but for security we don't want to give this permission .
so we need a work around
Create a role with required permission and then add users to that role.
*/
--Create user defined database role Readers
EXEC sp_addrole DBUser
-- Add this role to fixeddbroles to get database level permission
EXEC sp_addrolemember db_datareader, DBUser
EXEC sp_addrolemember db_datawriter, DBUser
GO
--------READY TO TEST --------
------ we are using this sample login for test
use master
Go
Create login testlogin1 with password='@@somepassword123'
use HTDBA
go
Create user testlogin1 for login testlogin1
--- now add this user to user created DBUser role .
EXEC sp_addrolemember DBUser, testlogin1
