RestrictSigninToPattern multiple domains

[Scott]

I  would like to use the "Restrict which users are allowed to sign in to Google Chrome" in a GPO (RestrictSigninToPattern).   Basically I want to restrict sign in to only "*@domain1.org" or "*@domain2.org".  Can I, and if so how, could I set the string for the two?

The closest I can find, is line 44 in this post https://gist.github.com/WardsParadox/9ba7cec7b40783d14e2b39dc3661c9d6

<string>.*@(domain1\.org|domain2\.org)</string>

But that doesn't work and seems to be for mobiles.

I'm having the same issue. I'd like to restrict to ".@contoso.com" and ".@contoso.onmicrosoft.com". Space, comma or semi colon doesn't work

Hi all - did either of you ever get this figured out? Having a similar issue and not sure if we should be trying regex at this point or not.

Thanks!

Looking at the source code of the policy the regex matches is a full regex matcher so anything that works in say https://regex101.com/ would work there to. For example for the domains listed by Fredrik this is a valid and minimal expression .*@contoso(\.onmicrosoft)*\.com alternatively this would work too .*@(contoso|contoso\.onmicrosoft)\.com

IF neither works please file a bug at crbug.com and also include the output in debug log that you will get when running chrome --enable-logging from the command line which should contain some information about what is not working.

Hope this helps Julian

This seems to be working for me:

(?:.*@domain1.org|.*@domain2.sch.uk|.*@mytenant.onmicrosoft.com)
