I'm not sure if this happens because of Catalina...
The following error appears if I try to launch any command with sudo:
sudo: unable to initialize PAM: No such file or directory
I cannot find any value 0x3f0 in the header file.
kLAPolicyDeviceOwnerAuthentication == 2
kLAPolicyDeviceOwnerAuthenticationWithBiometrics == 1
Where was this reverse engineered from ?
I'm running into some build issues on my M1 MacBook Air. After following the normal install process, I'm now unable to use sudo...
Once I've resolved that issue, I'd love to rerun the build script to get the console output to help further troubleshooting.
edit: resolved by enabling the root user and removing the touchid line.
Here's the output of sudo make install

It seems that something happened on 10.12.4 and broke things. I'm not sure what exactly changed, but I was suddenly unable to use sudo, it would only give the following error message:
sudo: unable to initialize pam: no such file or directory
The library however was still there at its usual location.
I had to enter single user mode and remove the pam_touchid line from /etc/pam.d/sudo to recover sudo access.
Is 2ba1922 perhaps an attempt to resolve this issue?
Doesn't work on macOS Big Sur even after changing the target to 10.16
sudo: unable to initialize PAM: Operation not permitted
