sshd PermitRootLogin problem

[Ido Admon <rhingael_(_at_)_start_(_dot_)_no>]

Hi list,
In short:
I set PermitRootLogin in /etc/ssh/sshd_config to 'forced-commands-only', as 
described in sshd_config(5), but when trying to log in (with public key
auth), I'm asked for a password and not allowed in ("Permission denied, please 
try again.").
If I comment this option (which defaults to 'PermitRootLogin yes') and HUP sshd 
then I'm let in without hassle (and without being asked for a password, i.e. 
the public key setup is ok)

So, 'forced-commands-only' doesn't work for me.
Invoking the client from another machine with or without a command argument, 
gives me the same result: password prompt and failed login (no, typing the 
right password doesn't let me in).

Server is on 3.6 prerelease (September 27th) and client is on 3.6-current 
(October 21st).
Here's the contents of sshd_config (only non-defaults), followed by the output 
of 'ssh -2 -vvv root_(_at_)_192_(_dot_)_168_(_dot_)_0_(_dot_)_1 date', any help appreciated:

Port 22
Protocol 2,1
ListenAddress 192.168.0.1
PermitRootLogin forced-commands-only
ClientAliveInterval 20
