Problem with overlay uniqe

[Ruud Baart <r.j.baart@prompt.nl>]

I use slapd 2.4.23 (debian package) with some overlays: syncprov, unique and valsort. I have a problem with the unique overlay.

This is the unique constraint:
olcUniqueURI: ldap://ou=Workstations,ou=Devices,dc=example,dc=com/?uid?sub

I try to add a ldif like this:

dn: uid=userabc,ou=MozillaAddressBook,ou=Users,dc=example,dc=com
objectClass: person
...
objectClass: organizationalPerson
objectClass: inetOrgPerson
objectClass: ..
...
uid: userabc
...

with ldapadd I get:

ldap_add: Constraint violation (19)
        additional info: some attributes not unique

When I remove the unique constraint the ldif file is accepted.

It seems to me that something is wrong: the base of olcUniqueURI is different from the base where I try to add a entry. I don't understand this. Is the olcUniqueURI wrong?
