That smells like cpanel modifies /etc/pam.d/ somehow? Can you please try a fresh installation where it works, back up /etc with sudo cp -a /etc /etc.bak, then install cpanel, run

diff -Nur /etc.bak /etc

and check/paste the diff? Please give it a check for passwords or other secrets first, the most interesting changes are probably in /etc/pam.d or /etc/nsswitch.conf.

Thanks!

I am in this same situation. Fresh Cloudlinux 9.4 Shared pro install. Enabled Cockpit, logged into cockpit with ROOT user. Fully updated Cockpit and all system updates via Web GUI. Activated Cloudlinux Installed cPanel

Cockpit GUI comes up, but I can no longer sign into it.

"wrong username or password"

No entries in the disallowed users file.

Seeking to be able to log back into Cockpit for routine server health checks.

Do you have any logs of with relevant pam failures? Does cPanel disable root login? It would also be helpful if you could answer the questions here https://github.com/cockpit-project/cockpit/issues/19865#issuecomment-1903318549
