Your cisco doesnt like certain attributes in the reply and closes the 
connections. Likely as not the attributes it doesnt like is the ones in 
relation to what your customer is trying to assign. debugs will show you 
exactly which one, but beware.

debug radius
debug aaa authentication
debug aaa authorization
debug aaa per-user
debug aaa subsys
debug ppp negotiation
debug vtemplate ev
debug vtemplate cloning
debug vprofile

I would also run your server in debugging mode to see exactly which 
attributes are being sent to your cisco nas for those users.
