I checked each of those files, and did not find anything that was abnormal. They listed “files”. Also the /etc/shadow file does exist and the root account is enabled.
Update: I switched to using CentOS 7.5 ISO rather than the most current CentOS 7.7 ISO. The CentOS 7.5 ISO does not have aforementioned issue, and I am able to upgrade from there to CentOS 7.7.

They should have "files" listed as the first entry. Oh, and also make sure that the /etc/shadow file exists and contains a root entry. And that it isn't disabled. Next, check the pam configuration (in /etc/pam.d). It may be missing a module to retrieve the root user. Of course, I could be way off base with those suggestions, somebody else may have better ideas. But your problem sounded like a low-level authentication issue. _______________________________________________________________________ Kevin Keane | Systems Architect | University of San Diego ITS | [email protected]<mailto:[email protected]> Maher Hall, 192 |5998 Alcalá Park | San Diego, CA 92110-2492 | 619.260.6859 | Text: 760-721-8339 REMEMBER!

I checked the archives and was unable to find anything related, so now I’m writing here. I am building a CentOS 7.7 stateless instance. When I deploy to a node, the node will boot but I am unable to log in as root from the console. I also added a user (via doing a chroot into rootimg and adding a user), but when I attempt to log in via said user on the console I get the error “User not known to underlining authentication module”. When I check the logs I get the below logs. Any help on this would be greatly appreciated. Thank you! Dec 12 17:21:00 cn1 systemd: INFO Starting Update UTMP about System Runlevel Changes...
