May ve very useful that the unique_base directive allow a list of subtrees where
check the uniqueness.
For example:
check the uniqueness of  the "uid" attribute in "dc=university,dc=edu" may
yields a "false" duplicate because:
  dc=university,dc=edu
allows only one uid but the same uid must be used in several subtrees (well and
only one, but in several subtress under dc=university,dc=edu):
  o=people,dc=university,dc=edu
  ou=mail,o=accounts,dc=university,dc=edu
  ou=smb,o=accounts,dc=university,dc=edu

so, if the unique_base evaluates a list of separate subtrees, the uniqueness
overlay may be useful, some like

unique_base o=people,dc=university,dc=edu
ou=mail,o=accounts,dc=university,dc=edu ...

I think this may be useful, because normally the person's uid should be the uid
in the services' subtree.
