[CalendarServer-dev] PyKerberos - allow more generic use of authClientGSSWrap

Hi! I'm using the pykerberos bindings that are developed as part of calendarserver to implement support for authenticating GSSAPI using FTP connections (RFC2228). However, at the moment, pykerberos appears to be making assumptions about the way Kerberos is used and forces some changes to the buffer passed into gss_wrap(). I need the attached patch to get it to work. How should I go about allowing more generic use? Would it be ok to break the existing API? Should I add a new call? Cheers, Jelmer --
