Thanks Roman!

I was able to reproduce this issue in 68.0.3423.0, after setting the flag and relaunch, Chrome keeps crashing.

However in 68.0.3425.0 with this fix I just cannot login:

Hey, could you please try again? We fixed several issues with login. I just checked on 10703 - setting flags works.
Thanks!

I wasn't able to login, looks like it keeps crashing while attempting to login as a user.

Thanks for the logs. Seems like a different issue, I filed a bug: https://bugs.chromium.org/p/chromium/issues/detail?id=845829

Hey Ivan, could you please try again with 10743.0.0+ image? Also could you grab a tcpdump.log during authenticate user? You need to run 'tcpdump -vvv -s 1600 -w tcpdump.log' in a root console before authentication. We're wondering why it is so slow, the log should help to investigate. Thanks!

You might have to install tcpdump and run with the -Z option:

- On a DEV device, open console.
- Enter 'dev_install' to install some dev tools.
- When it asks you to 'Install virtual/target-os-dev package now', enter
'N'.
- Enter 'emerge tcpdump' to install tcpdump.
- Enter 'tcpdump -vvv -i any -s 1600 -w /tmp/tcpdump.log -Z root' to record
network logs.
- Switch away from console, reproduce the authentication issue.
- Go back to console and hit CTRL+C to stop log collection.
- Send us the tcpdump.log file.

I was able to login and set flag on chrome://flags. No issues, marking this as "Verified" (authpolicy.log attached).

I could not install dev tools, looks similar to crbug.com/701955:
