We have a lab machine that is/was setup to allow someone to ssh to
the host as root, assuming the users public key has been added to
roots .ssh/authorized_keys.
This all worked fine under FC3. We upgraded the box to FC4, now no
one is able to ssh in as root. The following error is generated in
the /var/log/secure file:
sshd[6048]: fatal: Access denied for user root by PAM account
configuration
I've verified that the sshd_config file has not changed.
The /etc/pam.d/sshd file also has not changed.
I'm guessing this is something to do with authconfig or system-auth?
I've tried a couple of changes there, but no joy.
There are other PAM related problems, but if I can get this part
working, I don't have to worry about my connection dropping (since
the lab is difficult to access physically).
I would normally handle the need for root via sudo, but this is one
of those "special" circumstances. The box is strictly a target for
testing, resides by itself on an private, isolated /29 and is
physically hard to get to. For this particular setup, I have to be
able to come in via ssh as root. It's a long story. ;)
More than anything, I'm mostly interested in what has caused this and
how to fix, just as a point of curiosity.
Any help would be appreciated.
