I have trouble to decrypt the LDAP packets in the trace. Have you used Wireshark to do that? Did the packet 1848 define a delete operation on record #1 with LDAP_SERVER_TREE_DELETE_OID specified? Have you checked that both records are not in the AD any more after tree deletion ?

Subject: Behavior explanation on subtree delete control behavior with iscriticalsystemobject
I found an interesting problem
In MS-ADTS it is said:
220.127.116.11.5.7.2 Tree-delete Constraints
All regular delete operation constraints apply on each object being deleted.
The tree-delete operation may not be applied to an NC root.
Objects with isCriticalSystemObject attribute equal to true may not be deleted by the tree-delete operation (this also applies to objects in the subtree being deleted).
This constraint is checked
object-by-object, and deletion stops if some deletion would violate this constraint. Because, as explained in the next section, deleted objects never have children, the result after deletion stops due to this constraint is a tree. The resultant tree may not be the same as the original tree because some objects may have been deleted prior to the failure.
My understanding is that if you try to deleted an object that has the isCriticalSystemObject attribute set to TRUE or one of the object bellow in its tree then the operation should failed.
Did I get the meaning right ?
If so can you explain me how with this configuration:
./bin/ldbsearch -H ldap://172.16.100.27 -U administrator%totoTATA321 -b "CN=ARES,OU=Domain Controllers,DC=w2k8r2,DC=home,DC=matws,DC=net"
# record 1
dn: CN=ARES,OU=Domain Controllers,DC=w2k8r2,DC=home,DC=matws,DC=net
# record 2
dn: CN=RID Set,CN=ARES,OU=Domain
The delete with subtree control on the following trace at packet 1848 is working.
