T-SQL copy Logins, Users, roles, permissions etc

user394721 picture user394721 · May 12, 2011 · Viewed 24.8k times · Source

We have implemented log shipping as a database disaster recovery solution and want to know if there is a way I can use T-SQL to script all the logins, users, roles permissions etc to the master database on the secondary server so that the T-SQL can be sheduled to run as an SQL Job?

My aim is that in the event of a D/R situation we can simply restore the transaction logs for each database to the secondary server and not have to worry about orphaned users etc.

Thanks for you help!

There is a login copy script here designed to copy logins to another server for disaster recovery purposes:

Use master;

    Drop Procedure dbo.dba_CopyLogins

SET ANSI_NULLS ON
