Use this stored procedure to quickly capture all login information when needed, especially for security audit situations.

Managing login and DB user permissions is among the responsibilities that DBAs must take care of. To catch the permission of all Users in a database or all permissions of a certain login on all DBs, down to DB Object levels using SSMS is time consuming, tedious, even impossible, let alone instances with hundreds of databases. Especially, impersonated logins, which show no access on any DB, but they actually have access to hundreds DB objects like tables, view, Stored Procedures in several DBs in the instance. Use this stored procedure to quickly capture all login information when needed, especially for security audit situations.

What it does: This stored Procedure is to skim all login/DB Users in a SQL Server instance along with their DB permissions down to the DB object level. You can store the result set in a table and query the table to find out:

  1. All Database User accounts and all permission granted on a specific DB.
  2. Permissions of a specific DB User on a specific DB.
  3. All permissions that a certain login account possesses on all DBs in the instances.
