  You don't cache what the user entered, i.e. User-Password or EAP-GTC.  You cache the Cleartext-Password attribute which you received from the database.

  And why are you trying to cache EAP-GTC anyways?  Does the database disappear from time to time? If so, fix the database.

  You can't cache an Access-Accept for EAP.  It doesn't work, and it's *always* the wrong thing to do.
