I'd consider it, if I knew where to even 
begin to start looking!

The thing is, I just tried it where I 
changed the line for the alternate 
user in /etc/passwd to NOT execute the 
chroot shell, rather /bin/bash, 
like normal.

Guess what, it still happens!  What's 
going on, here?  It seems related 
directly to public key authentication, 
because this now works if I allow 
PasswordAuthentication and 

Also, changing back to chroot'ing with 
the empty password, it works.  It 
MUST be related somehow to the 
public key authentication.  Something 
isn't configured right, or a file is in the 
wrong place or wrong 
permissions, or something... maybe 
SSHD doesn't like a different user 
than the real UID, but you say that this 
works for you...
