Hello Kurt, Steve, vendors,

Noriko Hosoi of Red Hat notified us about the following
deficiency:

A possibility to bypass access control list (ACL) definitions was
found in the way 389 Directory Server performed LDAP modifyRDN
operation upon request from client. When a user has been granted
access to set of DN entries, but denied access to a specific subset
of those entries, it was possible the user to obtain temporary
(till next Directory Server restart) access to that subset of
entries (they should not have had otherwise ability to access) when
the DN entry was moved via database modify RDN function.
