Configuration:
- MMR with 3 nodes and normal syncrepl.
- slapo-memberof used to populate/update attribute 'memberOf' in user entries.

If a group entry is modified and slapo-memberof updates the attribute 'memberOf'
in the member's entry the contextCSN value of the server where the LDAP request
was sent to is not updated on the other MMR replicas.

All changes are correctly done though.

After restart contextCSN values are all the same on all MMR replicas.
