Update to Buchan Milne's 2.3.whatever (ours on RHAS4 is 2.3.30 using his 
older rpm specfile).

Ok, but only if that attribute is included in one of the objectClasses 
allowed by the respective schema that you've loaded.

See the above.

We do that kind of thing (and often) with a small (20 lines?) shell 
script using ldapsearch incorporating ldapmodify and a here document.

Now this was probably not the answer that you were hoping for, since the 
mindsets involved in SQL and LDAP are quite different. Nevertheless, 
it's the kind of script that, once you've got into the swing of things, 
will take you a couple of minutes to adapt. Though "getting into the 
swing of things" could cost you some time, just like learning SQL.
