Presumably your front-end is protected by standard Umbraco membership? In that case I'd approach it by creating a dummy Member (say "Back End User") that has permission to access all protected pages. A simple way would be then to give the back-end users the login details of this account. No coding needed :)

But if you really wanted it to be automatic, then you'd have to add some extra logic. Something like:

• In a master page / controller that runs on every request check if a back-end user is logged-in
• Then check if the Back End User member is already logged in (if so, no need to do anything)
• If not, then log the back-end user in programmatically (use membership service and forms authentication)

They should then have access to member pages. I think you are going to need a dummy member otherwise any calls to access member properties won't break, even if you get around authentication.

Then a lot of work awaits you, I fear. You'll probably need to write a custom membership provider and quite possibly have to modify the Umbraco core.

For instance, what if you have some code like this:

if (Members.IsLoggedIn())
{
   var member = Members.GetCurrentMember();
   <p>Hello @member.Name<p>
}

So if you fake the member being logged in then you will pass the Members.IsLogged() in check but then your code will blow up as there won't actually be a current member to access.
