Description of problem: 
Automembership plugin fails to create member attribute to the accosicated groups when entries moved from Non-automemscope to automemscope. This happens when the complete OU is moved from outside scope to automemscope or only the user entries moved from ouside scope to automemscope.


Version-Release number of selected component (if applicable): RHEL63.


How reproducible: Consistently.


Steps to Reproduce:
1. Install 389-ds-base 1.2.10.2 or the latest.
2. Configure automembership plugin. Refer the test plan - https://svn.devel.redhat.com/repos/DStetframework/trunk/testcases/DS/6.0/testplans/autoMembers/AutoMembersTestPlan.html
or the design doc - http://directory.fedoraproject.org/wiki/Auto_Membership_Design
3. Configure automembership plugin with automemscope set to "ou=automemscope,dc=auto,dc=com" and don't create "ou=automemscope" subtree.
Create few entries in "ou=nomemscope,dc=auto,dc=com" and then run modrdn operation to change the subtree "ou=nomemscope" to "ou=automemscope".
- Check whether member attribute created in the groups.
Result: No member attribute created in the groups defined in the plugin.

Actual results: Group's associated member attributes not created for the users.


Expected results: Member attribute should get created when entries moved from outside scope to automemscope.


Additional info: It fails even when the user entries moved from outside scope to automemscope.

Configure automembership plugin with automemscope set to "ou=automemscope,dc=auto,dc=com". Create subtree "ou=automemscope".
Create few entries in "ou=nomemscope,dc=auto,dc=com" and then run modrdn operation to change the user RDN value with new superior as "ou=automemscope".
- Check whether member attribute created in the groups.
Result: No member attribute created in the groups defined in the plugin.
