  Already installed :-/

  I have the same setup, except that I don't have NTLM or SDPS enabled.
My fetchmailrc contains the following:

poll brown via postoffice.brown.edu
  protocol KPOP
  auth kerberos_v4
  principal pop.brown
  preauth kerberos_v4
  user Daniel_Burrows

  (the "principal pop.brown" line is necessary -- our mailserver here expects
   you to ask for a ticket for pop.brown@BROWN.EDU rather than whatever
   the default is (I think it's postoffice@BROWN.EDU or something))

  This works perfectly if I build fetchmail against kerberos4kth; if I
build against krb5, it fails as I described ealier:

torrent:~> fetchmail -v
fetchmail: 5.9.0 querying brown (protocol POP3) at Sun 02 Sep 2001 09:05:07 PM EDT
fetchmail: kerberos error Principal unknown (kerberos)
fetchmail: POP3> QUIT
fetchmail: POP3< -ERR Kerberos authentication failure: Unknown protocol version number (kerberos)
fetchmail: Kerberos authentication failure: Unknown protocol version number (kerberos)
fetchmail: Query status=3 (AUTHFAIL)
fetchmail: normal termination, status 3

  I wonder if it's something strange about how the POP server here is
configured.  Anyway, in a year or so this won't be my problem 'cos I'll
be outta here, so it's probably not worth wasting too much time on :)
