Good morning Tridge! Since Hongwei is out of the office, I have created case 
SRX091112600056 to track our work against your question about rDN size / 
deleted object rDN.

I expect to be able to begin work on this tomorrow, and will keep you updated!

Tridge,



  The RDN of Deleted Objects container is a little different from the normal 
RDN.   The following information in MS-ADTS 3.1.1.5.5 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.



Thanks !

Hi Hongwei,



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:



  
CN=89532b80-09fe-445e-afef-965c0d7f7d15\0ADEL:462902b4-1824-4f02-8956-9f934f64fa01,CN=Deleted
 Objects,CN=Configuration,DC=vsofs8,DC=com



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 way?



Cheers, Tridge
