Good idea. Maybe it will clue one of you in, because I haven't been able 
to see where the failure is yet...

Here is the relevant output from ssh -vvv when it doesn't work:

debug1: Authentications that can continue: publickey,password,hostbased
debug2: userauth_hostbased: chost mimi.shadlen.org.
debug2: ssh_keysign called
debug3: ssh_msg_send: type 2
debug1: permanently_drop_suid: 1021
debug3: ssh_msg_recv entering
debug2: we sent a hostbased packet, wait for reply
debug1: Remote: Accepted for mimi.shadlen.org [10.208.108.17] by 
/etc/hosts.equiv.
debug1: Authentications that can continue: publickey,password,hostbased
debug1: No more client hostkeys for hostbased authentication.
debug2: we did not send a packet, disable method
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password

Here is the same relevant output from ssh -vvv in the case that it works:

debug1: Authentications that can continue: publickey,password,hostbased
debug2: userauth_hostbased: chost herbie.shadlen.org.
debug2: ssh_keysign called
debug1: permanently_drop_suid: 1021
debug3: ssh_msg_send: type 2
debug3: ssh_msg_recv entering
debug2: we sent a hostbased packet, wait for reply
debug1: Authentication succeeded (hostbased).
debug1: channel 0: new [client-session]
debug3: ssh_session2_open: channel_new: 0
debug2: channel 0: send open
debug1: Requesting no-more-sessions at openssh.com
debug1: Entering interactive session.
debug1: Remote: Accepted for herbie.shadlen.org [10.208.108.24] by 
/etc/hosts.equiv.
debug1: Remote: Accepted for herbie.shadlen.org [10.208.108.24] by 
/etc/hosts.equiv.
debug2: callback start

Regarding the authorized_keys files, I thought those were for key based 
authorization, rather than hose based authorization.
