Yes, it helps, thanks. 

Perhaps you can clarify a huge point of confusion ... I can do klist, etc. on the AD which
tells me that kerberos is accessible from other apps, presumably using the kerberos in Samba. 
Also, Dovecot uses GSSAPI authentication which, as I understand it, uses Kerberos.  So, why do
these things work, apparently with Samba's kerberos, but SASL and other such things do not?

If I install heimdal-dev or similar, will it interfer with Samaba?
