My Outlook from Office 2011 continually switches to Kerberos authentication.  Even though i go to setting _> accounts and switch it to name and password, it keeps switching back (every two to 5 minutes) and asking for my Kerberos login, etc.  anyone have any idea why it keeps doing this?  when i switch it back to name and password it works fine for , like i said, two to 5 min.  thx
