Hello, About two months ago I submitted an Enhancement patch for the PyKerberos component under Ticket #798 [1]. This patch is described in detail on the ticket, but essentially it introduces support for Python 3 while maintaining support for Calendar Server's minimum Python version of 2.6 [2]. Since I haven't heard anything, I thought I would request feedback for the patch directly. I have done some basic testing of the patch, but if there's more that I need to do to get it included, please let me know. Thanks, Alex Szczuczko [1] - https://trac.calendarserver.org/ticket/798 [2] - http://trac.calendarserver.org/wiki/HACKING#coding-standards
