If it is, I don't see it. There is no mention of managedsa or 
2.16.840.1.113730.3.4.2 anywhere in the chaining backend code. The only 
place it is mentioned is in the default list of nsTransmittedControls in 
the template-dse.ldif used during new instance creation.

It's not necessary, and I'm not sure where it is coming from. Once place 
might be an internal operation, but I'm not sure what internal operation 
would be doing this. You might also try to remove 
nsActiveChainingComponents and nsPossibleChainingComponents to see if 
one of those components is doing an internal operation with managedsait set.
