Hi. I also have been following this thread.

If the intent is to use simple bind, client changes don't seem necessary.
As Howard pointed out, {LM|NT} schemes can be added with a libutil 
backport
to OpenLDAP 2.1 from CVS. 

The synchronization issue can be solved by a plugin or by a proxy.
sambaLMPassword attribute can be synced to the userPassword
attribute either before bind or after password modification.
Another option is to use back-ldap, as SLAPI is not supported in OpenLDAP 
2.1.
Entries in the native backend have userPassword attribute and is shown to
the client with the sambaLMPassword attribute instead of it through the 
mapping
capability of back-ldap. The mapping works at both read and write.
(In fact, when I've been searching the OpenLDAP archive, I found a short 
discussion
on the attribute level aliasing, but couldn't find followups. Anybody 
knows the status ?)
