[CalendarServer-dev] Implementation of credential delegation in pyKerberos

Hi there, I'm not sure that this is the correct place to be posting this, but it's the closest I can find. I've implemented an extra function for python-kerberos that allows credentials to be cached and then used to authenticate to other services using said credentials. I am interested in pushing these changes upstream so that others can use this functionality and I was wondering how I'd go about doing this. Thanks, Joshua Warburton Irax Ltd.
