I am getting a "ldap_add: Local error" from ldap_modify when I attempt to
import the following LDIF file:

-------------
dn: cn=chainbe1, cn=chaining database, cn=plugins, cn=config
objectclass: top
objectclass: extensibleObject
objectclass: nsBackendInstance
cn: chainbe1
nsslapd-suffix: dc=mycompany,dc=net
nsfarmserverurl: ldaps://gigdev0062.mycompany.net:636
nsmultiplexorbinddn: cn=Replication Manager, cn=config
nsmultiplexorcredentials: testpass
nsCheckLocalACI: on
-------------

I also attempted to import the file via JXplorer and perl's Net::LDAP
module.  Both failed with the same error (Error 82, in the case of
JXplorer).  When I attempted to create the object with just the dn, cn and
objectclasses, it worked fine.

I am using JXplorer to browse the LDAP, which provides a schema browser for
whatever DB you are connected to.  It does not list the attributes I listed
above, but does show many of the other Fedora-DS specific attributes, as
well as custom object classes and attributes that we have added.
