When your app starts, you could ask the user for the user name and password necessary to access MSDE. These could be stored as memvars or application object properties while your app is running.

To test if the user typed them in correctly, rather than storing the username and passwords themselves, store MD5 hashes of them. It is easy to test if MD5Hash(< user's name or password >) is the same as the previously stored hashes, but almost impossible to back-calculate the user name or password from the hash value.
