I think providing openid access to ldap authentication sounds like
a good idea if you can be fairly certain that it isn't going to
introduce security problems. That is, are you pretty confident of
the stability of the PHP code used to implement this gateway?
Did you do this work referencing ldap.osgeo.org or the ldap used for
the telascience blades? I didn't think that the telascience blades
currently had access to ldap.osgeo.org at all but I could be behind
If you are actually working against the wrong ldap now I'd suggest
we give you a test.osgeo.org account (the secondary machine with
the same hardware configuration as www.osgeo.org) and you set it
up there, taking careful note of what would need to be moved.
The test.osgeo.org machine has access to ldap.osgeo.org, and is
configured quite similarly to the main machine so it should be easy
to migrate stuff over. Once completed, and migrated the
openid.osgeo.org would resolve to the main machine ... the same
system that has the ldap on it.

We aren't really too good at standardized look and feel, and I'd
suggest that doing this for the openid stuff could be pretty low

I gather you mean making use of forms like
Is that right?

Are you suggesting that there should be an informational page
similar to ldap_edit_user.py? Or is this something you would
do within the openid php stuff?

I'm willing to help a bit.
