LDAP preference storage with 2.3

[Michael Bull]

We're going to want to go this way with IMP at our location, so I'd like to 
do more with testing it.   I've started to go through the ldap driver code 
and the  impPrefsObject.ldap, but if someone could provide some default 
configuration info (such as the stuff for conf.php, or any other "defaults" 
I should be aware of for the LDAP server that would be expected) that would 
be great.

Just going through the schema, I'm wondering if attributes are 
missing.  I'm noticing in the 'allows' field that things like filters and 
some of the newer settings are missing, though I haven't fully got this up 
yet (today's task).

Any hints or pointers would be great; I'm happy to submit a patch with the 
updates to the schema as this moves on (I notice it hasn't changed since 
June, unless someone has gotten to it more recently than my CVS...).

Regards,
Mike.
