I missed the context here (the reply seems to have been cc'ed to 
secureshell but the original request wasn't).

OpenSSH 4.4 added a "Match" directive to sshd_config that allows per-X 
overriding of some configuration directives.  Authentications aren't 
supported yet but I have a patch that adds it which hopefully will be in 
the next release.  This would allow you to do something like the 
following for the user "sftpuser":

PasswordAuthentication no
Match User sftpuser
	PasswordAuthentication yes

If you're interested I can supply a copy of the patch that adds auth 
support (against 4.5p1).

usually comes from bad judgement.
