Following this wiki page: http://k5wiki.kerberos.org/wiki/Projects/Improve_GSSAPI_mechanism_configuration we need to support loading of /etc/gss/mech.d/*.conf files inside libgssapi and provide this as a patch to MIT for the next version.
Note this is NOT directly gssproxy related but a change in the libgssapi library.
Work is almost done, documentation updates are uploaded here: http://fedorapeople.org/cgit/gd/public_git/krb5.git/log/?h=master-mechdconf
Implemented upstream and added to Fedora packages spec file
