entryUUID vs DN

Question

When you need to refer to a precise ldap entry what do you prefer to use entryUUID or DN?

I have a grid. every item is a ldap entry. Every row in the grid has a checkbox which contains the item's ID. It could be entryUUID or DN. Which one would you use?

I would like to use entryUUID just to avoid situations like http://stackoverflow.com/questions/530247/new-directoryentrydistinguishedname-as-string-doesnt-work-when-dn-contains-a and to hook easily the selected item even if the user changes the CN. Of course using entryUUID means to pay attention in ldap backups and restores.

Any usefull tip?

Thank you
