I have F7 (fresh install in late June) on a Dell Latitude D610.
Just a few days ago, I stopped being able to 'su' or 'su some_user'
from a terminal: the passwords are no longer accepted. Same problem
to unlock a session (need to enter the password).
I can still login OK (as root or any user) from the initial login
screen or when switching user, or from a virtual terminal.
After one day of Googling, the only things I found meaningful to
report are the following:
That is what appears in my /var/log/secure file when I try to 'su -'
from a terminal from my account (cochard):
Jul 19 10:56:49 pcinvit10 su: pam_unix(su-l:auth): authentication
failure; logname=cochard uid=500 euid=500 tty=pts/12 ruser=cochard
rhost= user=root
and when I try to 'su test':
Jul 19 10:57:00 pcinvit10 su: pam_unix(su:auth): authentication
failure; logname=cochard uid=500 euid=500 tty=pts/12 ruser=cochard
rhost= user=test
Here are the contents of my /etc/sysconfig/authconfig file:
USEDB=no
USECRACKLIB=yes
USEHESIOD=no
USEWINBINDAUTH=no
USELDAP=no
USELOCAUTHORIZE=yes
USENIS=no
USESMBAUTH=no
USEWINBIND=no
USESHADOW=yes
USEKERBEROS=no
USELDAPAUTH=no
USEMD5=yes
USEPASSWDQC=no
USESYSNETAUTH=no
USESMARTCARD=no
FORCESMARTCARD=no
By comparing to the authconfig from my FC5 install, I tried to set
USELOCAUTHORIZE to 'no', and also tried to delete the lines with
USESMARTCARD and FORCESMARTCARD, but I noticed no change.
So I'm stuck here. Thanks in advance for any piece of advice for
investigating further.
