Hi everyone,

For an unknown reason the local login on my text terminals (login, pam) got screwed up somehow so that I cannot login to those terminals any longer (while I have no problems using KDE Konsole):

After having entered the username (any user and root) the password request appears but without any delay first a new password request is shown on the next line immediately followed by 'Login incorrect'.

The resulting terminal screen looks like this:

--------------------------------

Welcome to openSUSE Leap 15.0 - Kernel 4.12.14-lp150.12.28-default (tty1)


DOMAIN_NAME login: USER_NAME
Password:
Password:

Login incorrect

Welcome to openSUSE Leap 15.0 - Kernel 4.12.14-lp150.12.28-default (tty1)


DOMAIN_NAME login:


--------------------------------

This applies to all 6 terminals and happens at each login.

The journal has the following entries regarding per failed login:

--------------------------------

Dez 18 18:55:12 COMPUTER_NAME login[2341]: gkr-pam: couldn't get the password from user: Conversation error
Dez 18 18:55:13 COMPUTER_NAME login[2341]: pam_unix(login:auth): conversation failed
Dez 18 18:55:13 COMPUTER_NAME login[2341]: pam_unix(login:auth): aut could not identify password for [USER_NAME]
Dez 18 18:55:13 COMPUTER_NAME login[2341]: FAILED LOGIN SESSION FROM tty1 FOR USER_NAME, Authentication token manipulation error
Dez 18 18:55:16 COMPUTER_NAME systemd[1]: getty@tty1.service: Service has no hold-off time (RestartSec=0), scheduling restart.
Dez 18 18:55:16 COMPUTER_NAME systemd[1]: Stopped Getty on tty1
Dez 18 18:55:16 COMPUTER_NAME systemd[1]: Started Getty on tty1


--------------------------------

I have no idea what is going on here. I appears as if the delay for accepting the password is set to zero. However, I have no idea how that coudl happen and could also not figure out how this might possibly be repaired.

Any ideas?

Thanks a lot for your suggestions!
