I'm currently writing a database management application that connects to all of my databases and returns metadata for each database. The user currently has db_datareader role for MSDB but the DataReader .NET object only contains schema and no rows after executing a query on sysjobs or sp_help_jobs stored procedure in the code or in SSMS. I've tried granting execute and select on the database and object levels to no avail. When I give SA to the user it is able to return data, but I do not want to give the user SA.
What is the specific permission needed to retrieve the data from system tables and maintain the highest level of security?
