      Description

      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.

      -------------------------------------------------------------------------------

      1. create parent entry
        dn: ou=parent,dc=example,dc=com
        changetype: add
        objectClass: organizationalUnit
        objectClass: top
        ou: parent
      1. create child entry
        dn: ou=child,ou=parent,dc=example,dc=com
        changetype: add
        objectClass: organizationalUnit
        objectClass: top
        ou: child
      1. 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.
