I just tried this on Chrome 62 beta. 9901.54.0 

I made sure to Enterprise enroll using a Google account from a Google Domain with Active Directory 

Steps to repro:

1) Enterprise enrolled  
2) See "Join Device to Domain"  screen
3) Go to crosh>  
4) authpolicy_debug 3   

Results:

Same error"  The name org.chromium.AuthPolicy was not provided by any service files. "

Can you check whether authpolicyd is running in ps? I would have expected yes, but the error indicates it's not running. When I tried here, it did run. Strange.

If it's NOT running, enter this:

echo "3" > /run/authpolicyd/flags_default_level

This does the same as authpolicy_debug 3 would do if authpolicy was running. You might have to create the folder first if it doesn't exist. Then repro the problem and check authpolicy.log. It should be significantly longer and contain stuff like

disable_seccomp  OFF
log_seccomp      ON
...

If you see that, it worked.

I don't see authpolicyd running.  



Chrome OS: 62.0.3202.74 Beta 9901.54.0 Kevin device. 

Here's a video showing the Enterprise Enrollment and the AD "Device Join" screen and then going to the shell to check for authpolicyd via ps, and then trying to set the debug .

What version is the chromad team testing on? 

WAI, kinda. Kevin is an ARM board (aarch64) and we currently don't support ARM (and we do a terrible job messaging this). Authpolicy only runs on x86-64 and it just won't start on ARM or 32 bit x86. I'll file a bug to add an error message in Chrome.

Can you confirm that it works on an x64 board?
