Re: AUTH_FAIL_PUBKEY(failed in publickey authentication)

Hmm... that's an old version.  Perhaps this is not a new issue.

 

Can you confirm that this is happening only on that system? and that it was working before? (or perhaps this has been an old issue);  if it was working, what happened between it worked vs. now?

 

My advice (because this seems to be  a local issue, based on your description) is that you do an SSH trace and find the root of the problem.  In addition, the whole idea about using a solution like Centrify for UNIX/Linux is to consolidate the identity sources.  If you have users signing-in with their AD credential (username/password or Kerberos SSO) AND with SSH keys, this is a redundancy that causes these types of errors.

 

To do an SSH trace, do the following:

 

 

  • In the server exhibiting the issue, run sudo /usr/share/centrifydc/sbin/sshd -ddde -p 2222 to start the SSHD server in the foreground with verbosity turned on.
  • From the ssh client, connect to the SSHD server on port 2222,
    ssh -p 2222 -vvv <hostname>
  • Pay close attention to the session on the server

 

 

Most of the time, the issue may be related to the user not typing the password correctly, or simply a configuration issue.

 

Please note, since you're using Express, the current community supported version is 5.4.x and Centrify-enhanced OpenSSH is an optional component.
