I used to use auth sufficient pam_tid.so
in the /private/etc/pam.d/sudo
file to allow fingerprint authentification when using sudo
command.
Recently upgraded my NBP for a new M1 under MacOs BigSur (11.1), and the change still works.
However, suddenly, this stopped working. Intead of asking for fingerprint, it asks me for password in the GUI (not in the terminal).
After digging around, I did a MacOS recovery install and it resolved the problem.
Today, the problem appears again but the recovery install didn't fix it.
Has anybody an idea on what's going wrong ?
EDIT:
- I just discovered that this only happens when my MBP is docked to my docking station with 4 external screens and hard drive. I need to understand what is causing this issue, I guess this may be related to the display link USB video driver.
EDIT2:
- I confirm that the problem is related to Display Link drivers. I opened a support request here: https://support.displaylink.com/forums/287786-displaylink-feature-suggestions/suggestions/42614770-bug-sudo-with-touchid-disabled-when-using-a-docke
Thanks
