Probably not the best list to ask this question, but I will try anyway.

Can we expect to gss-proxy in RHEL-7?
The thing is that I would like to let Linux-based dhcp server to update windows based DNS server via gss-tsig updates and hate 'chgrp dhcpd /etc/krb5.keytab' dirty hack.

I guess sssd should use gss-proxy as well.
