Thanks.  When you get to this, look into the existing support Jelmer
added for using a system Heimdal in
source4/heimdal_build/wscript_configure, and extend that with the
configure tests from source3/wscript.  The magic ./configure like will
look like:
./configure --bundled-libraries=\!krb5,\!gssapi,\!com_err

With guaranteed option of either a very modern MIT kerberos or the
in-tree Heimdal, we should be able to make some good assumptions about
the capabilities of our kerberos libs, which will help the long-term
maintenance here.
