I figured that was the next step; I did note that if I manually
entered the right data, either via ldapmodify or host-mod with a full
dn, it worked fine but then displayed the entire dn in the UI, so I
assumed there was another bit to make that conversion and just hadn't
looked ahead for it.

The file as it is now is here:
http://www.astro.princeton.edu/~huston/astrocustom/astrocustom.1144.py.html
(take off the .html for the source file if you prefer).

And the error when I run 'ipa host-mod syrinx.astro.princeton.edu
--owner=huston' is:

To test the new parts, I then did an ldapmodify to set the owner
attribute, and 'ipa host-show syrinx --all' gave this error:
