 Posted: Sun Jan 28, 2024 12:57 pm Post subject: Xlock unlock fails if password contains special characters |
 |
|
I've tried searching and found nothing relevant to my issue, but my apologies if I've missed something.
With a password containing the Danish letters æ/ø/å unlocking xlock fails with the message "failed unlock attempt on user <username>".
If the password is set to something containing only these a-zA-Z0-9, xlock unlocking works fine.
Logging in via terminal and ssh works fine with both passwords mentioned above.
| Code: | /var/log/auth.log:
Jan 28 13:34:52 jessica unix_chkpwd[7743]: password check failed for user (<username>)
Jan 28 13:34:52 jessica xlock[7734]: pam_unix(xlock:auth): authentication failure; logname=<username> uid=1000 euid=1000 tty=:0.0 ruser= rhost= user=<username>
Jan 28 13:34:54 jessica unix_chkpwd[7748]: password check failed for user (root)
Jan 28 13:34:54 jessica xlock[7734]: pam_unix(xlock:auth): authentication failure; logname=<username> uid=1000 euid=1000 tty=:0.0 ruser= rhost= user=root

I don't know if it's a fallback that it also tries to unlock as the root user, but I've not done anything as the root user in this scenario.
I've tried recompiling xlockmore and pam (and rebooting afterwards) but the problem persists.
Any help will be greatly appreciated.

* Found these USE flags for sys-libs/pam-1.5.3:
U I
- - abi_x86_32 : 32-bit (x86) libraries
- - audit : Enable support for Linux audit subsystem using sys-process/audit
- - berkdb : Build the pam_userdb module, that allows to authenticate users against a Berkeley DB file. Please note that enabling this USE flag will create a PAM module that links to
the Berkeley DB (as provided by sys-libs/db) installed in /usr/lib and will thus not work for boot-critical services authentication.
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
+ + filecaps : Use Linux file capabilities to control privilege rather than set*id (this is orthogonal to USE=caps which uses capabilities at runtime e.g. libcap)
