I found out, that the problem lies in the permissions of /etc/shadow resp. /sbin/unix_chkpwd
I assume, /etc/shadow should be owned by the group 'shadow', but for some reason it had this permissions: $ ls -l /etc/shadow -rw-r----- 1 root root 1133 2008-10-06 19:32 /etc/shadow after doing $ sudo chgrp shadow /etc/shadow it worked, as the program 'unix_chkpwd' has the GUID bit set and is owned by the group shadow: $ ls -l /sbin/unix_chkpwd -rwxr-sr-x 1 root shadow 30272 2008-09-23 09:06 /sbin/unix_chkpwd This should be fixed for hardy & intrepid, as I had this problem on both versions and there are various bug reports out there about similar problems (e.g. #92932) regards, tom -- [intrepid] xscreensaver unlock fails https://bugs.launchpad.net/bugs/279560 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
