make sure you have
PermitRootLogin yes
or better
PermitRootLogin without-password
and also
PubkeyAuthentication yes
in sshd_config
Also, valid authentication methods can be restricted on the client side
via ssh_config as well as on the command line.

Hi folks,
we have a very weird phenomenon:
On two of our RedHat EL4 Update 4 servers root cannot login via ssh
using public keys. All other users can. root is asked for a password
instead.
sshd_config is RHEL4 default (that means pubkey auth allowed etc.),
and the rest is as well. The public keys are correctly appended to
/root/.ssh/authorized_keys. Rights on .ssh and its files are correct.
I have even tarred+gzipped and copied roots .ssh directory to another
server and tested there.
I have compared lots of things (sshd_config, pam config, even roots
.bash_profile) to a reference system where it works - everything I
have thought of is exactly the same.
PubkeyAuth has worked fine on the problem servers, but one of the
admins must have changed something, and of course no one remembers
anything. I am sure it is something small and silly I overlook.
Any hint and help is appreciated.
Dirk
