> Running the following LDIF causes an infinite loop (100% CPU of the ApacheDS process), the client waits for response. The two entries are created, the moddn operation then hangs.
> -------------------------------------------------------------------------------
> # create parent entry
> dn: ou=parent,dc=example,dc=com
> changetype: add
> objectClass: organizationalUnit
> objectClass: top
> ou: parent
> # create child entry
> dn: ou=child,ou=parent,dc=example,dc=com
> changetype: add
> objectClass: organizationalUnit
> objectClass: top
> ou: child
> # now do something bad: make the parent a child of its own child
> dn: ou=parent,dc=example,dc=com
> changetype: moddn
> newrdn: ou=parent
> deleteoldrdn: 1
> newsuperior: ou=child,ou=parent,dc=example,dc=com
> -------------------------------------------------------------------------------
> I'd expect an error, OpenLDAP for example returns "error code 53 - cannot place an entry below itself"
> Another problem: When I kill the server and start it again, the two inserted entries are not visible studio, but when trying to add them I get an "error code 68 - ENTRY_ALREADY_EXISTS". Seems loke the indices got corrupted.
