Set Level Permission in relational database

[Regina_Oliveira]

I need to ensure that the user accesses a library that is configured for a SQL database has the same permission that the user already has in the SQL SERVER environment.
How to do?

Thanks so much in advance.

How do your users currently access SQL Server? If they use Windows Authentication - automatic authentication with their Windows account - then you can apply the same technique when accessing a SAS library accessing SQL Server.
