This was my first idea, but I think in this specific case, it would be a 
bit complex to manage : a memberof attributeType has references to many 
potential DNs, and as SP are only activated when a modification occurs, 
it would have to check all the places in the server which potentially 
holds a memberOf attribute and control if it contains one of the moved 
entry's DN.

Instead of what having a computed memberOf AttributeType would easily 
solve the problem: you keep a reference to the entry, and rebuild the DN 
on the fly.

Note that with a SP, we could do the exact same thing except that we 
don't execute a SP when processing search requests...

The best solution would of course to have a SP which is associated with 
the entry containing the memberOf, and does the lookup (a computed 
memberOf attribute, sort of)
