How to enable Auto Logon for Google Chrome without prompt

Check the details of the Integration Authentication in this Chromium documentation:

http://www.chromium.org/developers/design-documents/http-authentication

With Integrated Authentication, Chrome can authenticate the user to an Intranet server or proxy without prompting the user for a username or password. It does this by using cached credentials which are established when the user initially logs in to the machine that the Chrome browser is running on. Integrated Authentication is supported for Negotiate and NTLM challenges only.

Basically, execute Chrome with these switches to specify the auth schemes:

Chrome.exe --auth-server-whitelist="MYIISSERVER.DOMAIN.COM" --auth-negotiate-delegatewhitelist="MYIISSERVER.DOMAIN.COM" --auth-schemes="digest,ntlm,negotiate"

I tried running the command line but it wasn't working. I had to configure the same settings via the Windows Registry:

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google][HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]"AuthSchemes"="basic,digest,ntlm,negotiate""AuthServerWhitelist"="*domain""AuthNegotiateDelegateWhitelist"="domain,server.domain.com"

Then I Killed Chrome (cmd line: TaskKill /im chrome.exe) and restarted chrome and tried again and voila. Everything worked as expected.
