Comment(by djflux):

 Yes, I'm using krb5.  I am now logging in successfully with Kerberos and
 can see other clients.  I cannot IM others and they cannot IM me.  The
 debug log shows the SIPE sends a 501 Not Implemented in response to an
 INVITE request, and I believe there is a 501 in response to an ACK when I
 initiate an IM from PIdgin.  Have to check my logs on that one.

 I do see presence notifications in the debug log though, although they
 don't change the status icon in Pidgin because they are all basic-status
 open.


 {{{
 (22:03:35) sipe: process_incoming_notify: body(<?xml version="1.0"
 encoding="UTF-8"?>
 <presence xmlns="urn:ietf:params:xml:ns:pidf"
 xmlns:ep="urn:ietf:params:xml:ns:pidf:status:rpid-status"
 xmlns:ci="urn:ietf:params:xml:ns:pidf
 :cipid" entity="sip:administrator at flux.local" >
 <tuple id="0" >
 <status>
 <basic>open</basic>
 <ep:activities>
 <ep:activity>busy</ep:activity>
 </ep:activities>
 </status>
 </tuple>
 </presence>
 )
 }}}


 OCS uses Enhanced Presence so the <ep:activity> tag shows busy or away.

 I added a sipmsg_find_auth_header since there are 2 WWW-Authenticate
 headers and the Kerberos header is never found and NTLM is always used.
 I've added a bool checkbox to indicate we want to use Kerberos.  Not sure
 if this is the "correct" or "preferred" way of doing things, but
 ItWorksForMe(tm).

 Although I've taken many computer sci/programming classes and have
 contributed code to other open source projects, I am very much a novice C
 coded so take my code with a grain of salt.  As I said ItWorksForMe(tm)
 but it's probably not too pretty.

 Did you checkout the mob branch lately with my gaim_ -> purple_
 conversions before you fixed you SSL things?  If not, I'll check your
 commit out and convert the gaim references, check back in, then add my
 Kerberos stuff.
