MFA redirect error when not SuperUser (v2.1.0, v2.2.1, v2.2.2)

I enabled MFA for a client using ZC 2.1. Several users now get a too many redirects error when logging in. In troubleshooting, it only happens with users who are not SuperUsers. I don't see this mentioned as a fix in 2.2. Is this an unknow bug?

Thank you,
Jim

I went to report this as a known bug, but the thread is closed. The MFA page is not allowed for any user profile but Super Users and it's not listed as a page in the profile editor. We had to add the page to the admin_pages_to_profiles table.

In admin's init_admin_auth.php file, does adding FILENAME_MFA to the array solve the problem?

        // check page authorization access
        if (!in_array($page, ['keepalive', FILENAME_DEFAULT, FILENAME_ADMIN_ACCOUNT, FILENAME_LOGOFF, FILENAME_ALERT_PAGE, FILENAME_PASSWORD_FORGOTTEN, FILENAME_DENIED, FILENAME_ALT_NAV], true)
            && !zen_is_superuser())
        {

I've already implemented a fix for this client site so can't try this fix there. I think I have a ZC 2.1 test site I can try this on.

I tested this on my demo 2.1 installation and it does work. Thanks for the help.
