Which key type gets selected?

["Henry B. Hotz" <hotz@jpl.nasa.gov>]

Suppose an as-req-equivalent comes in and it's restricted to, say,  
des-cbc-crc.

Suppose you have three of those keys in the DB.  One each with the V4  
salt, the AFS salt, and the V5 salt.

Which one gets returned?

Obviously you would *like* it to return the V4 one if it's a K4  
request, the AFS one if its a kaserver request (rx over 7004), and  
you'd like it to return the V5 one if it's a K5 request.  I don't  
offhand see how the code decides.  I'd also like to trace what the  
backup is if one of the types is missing.
