Hi!

I went through the design document and the related email thread here on 
the list and I have few questions:

1. Is there any progress on what's to happen if MODRDN would colide with 
an existing alias on a different entry?

2. How does this RFE change the behavior of stage user plugin? Is the 
principal (as in the canonical name) assigned at this stage of user 
lifetime?

3. Will there be any constraints on what string can be used as an alias? 
(The document mentions email address as one use case)

4. Will this RFE have any impact on AD trust (possibility of cross realm 
routing, RFC 6806 section 9)

Otherwise the document looks good from my POV as QE.
