            Bug ID: 410700
           Summary: kmail no longer allows addition of gmail account
           Product: kontact
           Version: 5.7.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: mail
          Assignee: kdepim-bugs at kde.org
          Reporter: Ekkehard.Blanz at gmail.com
  Target Milestone: ---

SUMMARY
kmail no longer allows me to create a new gmail account using the standard
method where authentication is "gmail," giving me the following error message:

"Sign in with Google temporarily disabled for this app
This app has not been verified yet by Google in order to use Google Sign In."

The workaround, using a "Custom Account..." also does not work as it insists
that the authentication method be "gmail" as soon as I enter imap.gmail.com as
the IMAP server, but, as mentioned above, this method does not work.  I need it
to be "PLAIN" to work.

STEPS TO REPRODUCE
1. Select "Configure KMail"
2. Click "Add..."
3. Select "Custom Account..." and select IMAP E-Mail Server
4. Enter "imap.gmail.com" as the IMAP Server
5. Since every further choice is grayed out, click "OK"
6. Go through the Google sign-in process and observes the error message

"Sign in with Google temporarily disabled for this app
This app has not been verified yet by Google in order to use Google Sign In."

OBSERVED RESULT
As soon as "imap.gmail.com" is entered as the IMAP Server, the Password field
is grayed out, and in the "Advanced" field, "Authentication" is fixed to
"Gmail", which then fails to authenticate

EXPECTED RESULT
a) When Google authentication is offered, it should work.
b) In the "manual" or "Custom" mode, I should be in full control and enter
"Plain" in the authentication method instead of "gmail," so I can work around
the bug in a)
