Bug 708824 – sys-apps/systemd: login with usernames including a dot (".") automatically closes gdm session due to pam_systemd forbidding it

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Oliver Welter 2020-02-09 12:11:25 UTC]

Looks like the username including a dot causes an error for creating the session.

See in attached log:
Feb 09 12:03:01 cloud gdm-password][99754]: pam_systemd(gdm-password:session): Failed to get user record: Invalid argument
Feb 09 12:03:01 cloud gdm-password][99754]: gkr-pam: unable to locate daemon control file


Reproducible: Always

Steps to Reproduce:
1.Create a user with a dot in it, e.g. "tony.stark"
2.Set a password for the user "tony.stark"
3.Login via gdm
Actual Results:  
The screen blanks and then the login screen is shown again.

Expected Results:  
The desktop is of the user is shown.

Is there an upstream bug report?

Just created one: https://gitlab.gnome.org/GNOME/gdm/issues/559

It looks to be a pam_systemd issue
https://github.com/systemd/systemd/pull/13244

What systemd version are you running?

I can reproduce the pam_systemd issue with sys-apps/systemd-245_rc1-r1.

Feb 22 13:22:05 naomi sshd[2623165]: pam_unix(sshd:session): session opened for user tony.stark(uid=10001) by (uid=0)

[Comment 6 Oliver Welter 2020-02-22 18:54:24 UTC]

I'm using sys-apps/systemd-245_rc1-r1 as well.

[Comment 7 Mike Gilbert 2020-02-22 19:17:03 UTC]

I'm working on a patch.

[Comment 8 Mike Gilbert 2020-03-05 16:32:07 UTC]

Should be resolved in systemd-245_rc2.
