This is also happening to me from time to time. But in my case, I added
users through Qluman, as described in the docs.
These are the last lines of the /var/log/auth.log file on the FE node,
right after the login attempt.
...
> sshd[9118]: pam_unix(sshd:auth): authentication failure; logname= uid=0
> euid=0 tty=ssh ruser= rhost=10.0.2.159 user=*********
> sshd[9118]: pam_sss(sshd:auth): authentication failure; logname= uid=0
> euid=0 tty=ssh ruser= rhost=10.0.2.159 user=*********
> sshd[9118]: pam_sss(sshd:auth): received for user *********: 7
> (Authentication failure)
> sshd[9118]: Failed password for ********* from 10.0.2.159 port 40398 ssh2
I've omitted the username and the timestamps and hostname columns from the
lines above.
Does anyone have any clue what might be going on? Do I need to show
anything else?
