.CreateReport using another credentials

I have an asp/asp.net application that uses forms authentication to
autheticate to the report server. My app constructs the url to access the
reports. No one has access to the report manager. Everything works great.
Now I've created a .net module that gets a report from the report server,
modifies it and deployes back to another folder. Its like an ad hoc solution.
For security reasons each role only has "View Report" permission. To do all
the backend stuff described in my "ad hoc" solution i'm forced to grant more
permissions such as create, delete datasources, reports to these roles. Is it
possible to programmically logon as a another user, get the report, modify it
and redeploy(.createReport)? This way my module has permissions to do this
and not the user. I'm using forms authentications. Does this make sense?found a solution:
