#12631: GSSAPI Authentication fails when using Heimdal
-------------------+--------------------------------------------------------
Reporter:  bill3i  |        Type:  defect        
  Status:  new     |   Component:  libpurple     
 Version:  2.7.3   |    Keywords:  GSSAPI Heimdal
-------------------+--------------------------------------------------------
 Our jabber server using GSSAPI authentication.  I am able to successfully
 connect to the server when using MIT's kerberos support, but I get a
 failure when using Heimdal kerberos.   This has been tested with Pidgin
 2.6.6 and 2.7.3.  The OS is ubuntu lucid.  The versions of GSSAPI are the
 stock lucid packages.  Here is a snipet from the debug log.  (The complete
 log is attached.)
