Would you consider merging my patch if I removed the extra attributes
(which I don't use yet)?
I was considering that the HDBentry in the hemidal database would simply
not change, but that when using LDAP we would present a 'richer'
interface. Otherwise, your proposal certainly makes sense.

I assume this will be 'off by default' before the security nuts jump all
over you :-)

How much 'samba stuff' are you willing to tolerate in Heimdal?
For example, once we start updating the 'last change time', we should
also update/honour the 'min password age' and 'must change time'
attributes. (Ie, query the directory for those properties, and set them
when we update the password).
It is a slippery slope, and I understand why many projects would run and
scream, but I would love to see Heimdal as the KDC companion to Samba.
(but that's simply because your HDB has at least made it sane for me to
do it :-)
