Troubleshooting¶
Logging¶
authd and the brokers are all logging to the system journal.
For authd entries, run:
journalctl -u authd.service
For the MS Entra ID broker entries, run:
journalctl -u snap.authd-msentraid.authd-msentraid.service
For the GDM integration:
journalctl /usr/bin/gnome-shell
For anything else or more broader investigation, use journalctl.
Logging verbosity¶
You can increase the verbosity of the logs in different ways.
PAM module¶
Append debug=true to all the lines with pam_authd_exec.so or pam_authd.so in the PAM configuration files (common-auth, gdm-authd…) in /etc/pam.d/ to increase the verbosity of the PAM messages.
NSS module¶
Export AUTHD_NSS_INFO=stderr environment variable on any program using the authd NSS module to get more info on NSS requests to authd.
authd service¶
To increase the verbosity of the service itself, edit the service file:
sudo systemctl edit authd.service
Add the following lines to the override file and make sure to add -vv at the end of the authd command:
[Service]
ExecStart=
ExecStart=/usr/libexec/authd -vv
Then you need to restart the service with sudo systemctl restart authd.
GDM¶
Ensure the lines in /etc/gdm3/custom.conf are not commented:
[debug]
# Uncomment the line below to turn on debugging
# More verbose logs
# Additionally lets the X server dump core if it crashes
Enable=true
Then you need to restart the service with sudo systemctl restart gdm.
authd-msentraid service¶
To increase the verbosity of the broker service, edit the service file:
sudo systemctl edit snap.authd-msentraid.authd-msentraid.service
Add the following lines to the override file and make sure to add -vv to the exec command:
[Service]
ExecStart=
ExecStart=/usr/bin/snap run authd-msentraid -vv
You will then need to restart the service with snap restart authd-msentraid.
Switch the snap to the edge channel¶
Maybe your issue is already fixed! You should try switching to the edge channel of the broker snap. You can easily do that with:
snap switch authd-msentraid --edge
snap refresh authd-msentraid
Keep in mind that this version is not tested and may be incompatible with current released version of authd. You should switch back to stable after trying the edge channel:
snap switch authd-msentraid --stable
snap refresh authd-msentraid
