[cifs-protocol] limits on rDN size in AD ?

The RDN of Deleted Objects container is a little different from the normal RDN. The following information in MS-ADTS 22.214.171.124.5 describes the composition of RDN for objects in Deleted Object container:
"The RDN of the object is changed to a "delete-mangled RDN"-an RDN that is guaranteed to be unique within the Deleted Objects container. If O is the object that is deleted, the delete-mangled RDN is the concatenation of O!name, the character with value 0x0A, the string "DEL:", and the dashed string representation ([RFC4122] section 3) of O!objectGUID."
It looks like to me that for the Delete Objects container, the size constraint should be dependent on the combination of the each sub component. Since I am out of office, I will ask one of my team member to investigate and confirm the behavior.

We're back to the old question of rDN size limits again!
I just got a DRS replication reply from w2k8-r2 with a CN that has a
length larger than 64. So I suspect that things are a bit more complex
than what we'd discussed before.
The object was:
which gives a length of 80.
Are we perhaps supposed to interpret the \0 as a termination character
for the purposes of this length constraint? (note that this is a \
followed by a 0, not a nul byte).
Or perhaps deleted objects are special in their constraints in some
