Removing Individual logins

  • Hi,

    We are planning to remove the individual logins in our sql servers in all the test environments first and later in production. Incase the user requests for his login we want to restore his login.Can you tell me how to do this as there will be different db's with different objects and diff permissions on different objects

    Thanks

  • Re-instituting the logins portion (getting access to the SQL Server itself) is fairly straight-forward:

    However, permissions within the database are another matter entirely. You could script out the database including permissions using the given tools. The problem there is how do you separate each individual user's permissions? For your databases, were permissions defined against individual users or were they assigned against database roles?

  • Hi,

    Mostly by roles. But for some users they were given individually. Can you give me the script to this or any tool.

    Thanks

  • SQL Server Management Studio will do the scripting but it's geared towards objects. There's also Scriptio, but it too is more geared towards objects:

    Then there are the 3rd party tools like Apex SQL Doc and Red Gate's SQL Compare.

  • I have the following which targets a specific user, but you could easily adapt it to traverse all database principals with

    where type in ('S','U','G')
