Write auxiliary data when updating/creating objects
Some LDAP implementations rely on special state objects to track IDs. An example is Puavo's ID tracking object:
cn=IdPool,o=puavo
objectClass: top
objectClass: puavoIdPool
cn: IdPool
puavoNextRid: 3
puavoNextDatabaseId: 1
puavoNextKadminPort: 10004
puavoNextGidNumber: 10007
puavoNextUidNumber: 10005
puavoNextId: 17
We need a method to update values in such ID objects when modifying the tree from AlekSIS.
