Hello
I modified my patch to slapo-constaint. The constraint can now be written as a LDAP url, which allows much more flexibility:
Usage example: constraint_attribute title uri ldap:///cn=titlecat,dc=example,dc=net?title?sub?
Here is the new patch: ftp://ftp.openldap.org/incoming/manu-070918.patch
Comments are welcome. I'll now write a man page.
