data source settings greyed out and user specific settings

I am using RDM with Microsoft SQL server and have been configured as db_owner for the database that is used for our passwords. Yet when I login and to administration>data source settings to see what the encryption settings are, I can't because the entire menu bar under administration is greyed out. Why is this greyed out, what other access do I need to have the ability to configure users and data source settings. I am using integrated authentication with the SQL server. I am trying to find what encryption settings are used for data that is stored in the database and where in the database is the passwords stored when using SQL to validate.

Also, when setting user specific credentials where is this information stored? Help says user specific local settings are stored in the user profile, so I am assuming the standard user specific settings are stored in the database. If so what type of encryption is used, what key is used and where is that stored?
