IMP 2.3 (the development version) has made quite a few strides toward this
goal, but the short answer is, I don't think it's all there yet.

IMP 2.2 (the production version) basically uses a database to store three
things:  (a) PHPLIB session data, (b) a primitive address book, and (c)
user preferences.

In IMP 2.3:

(a)  ...we've switched away from PHPLIB to use the built-in session
support provided by PHP 4.  I don't honestly know if LDAP is supported for
this, but you can use shared memory, which would eliminate the need for a
database for this item.

(b)  ...the contacts (address book) functionality is being moved to
another Horde module:  Turba, a new, more advanced contact manager.  I
know that LDAP will be supported for that, so that eliminates database for
that also.

(c)  ...there is a new user preference system that Jon's been working on,
and it supports LDAP storage.

Have I missed anything?  :-)

I take it you're using IMP 2.2 (Horde 1.2) for this test, then?  We don't
support LDAP storage for PHPLIB session data... at least, I've never heard
of anyone who's tried, there aren't any hooks for the Horde session class
for LDAP, etc.

I think with your focus on LDAP, you'd be best off looking at 2.3.  The
push is on to freeze the feature list and get an initial (probably
rough) release out soon.  Details on the <dev@lists.horde.org> list.
