Re: Password change redirect limitations

I worked with support, and with our account team, and they came to the
conclusion that this is "expected behavior" - I have suggested that they
update their documentation

SAML is on our roadmap

Frank,
We used to sync passwords from AD to Google many years ago and we had
similar issues. If you follow the steps under "Prevent users from
changing their Google passwords
<https://support.google.com/a/answer/2611842>", G suite should honor your
request. Support should help you or at least let you know that this is the
expected behavior.
I agree that moving to SAML will eliminate this problem and others so you
should consider that path for the future.
Good luck,

Rodolfo

If I am reading this correctly you are not using SAML.  I think that
would resolve this, obviate the need to sync passwords at all, and simplify
your user support for password management.

***** EXTERNAL EMAIL *****

Hi Folks, I've just spent the last couple weeks going back and forth with
Google Support, and our Higher Education Google person, and I figure I
should let these groups know the result of this.



Background:

   - We sync passwords from Active Directory to G-Suite using the
   Password Sync Tool on all Domain Controllers
   - We have the appropriate settings from
   https://support.google.com/a/answer/2611842
   
<https://urldefense.proofpoint.com/v2/url?u=https-3A__support.google.com_a_answer_2611842&d=DwMFaQ&c=bKRySV-ouEg_AT-w2QWsTdd9X__KYh9Eq2fdmQDVZgw&r=Lgw4Sh6g47kM5A_tpEcLZDyPGvmOKdeDlyp60PwA78c&m=jCRqsxx367xKALFP2zSW6frwizJx1CtTarGJiCfJdsk&s=HFw97xa0C9fPftyPL9TmuI6lUt9XBlixELV98rQEb8M&e=>
   configured to "Prevent users from changing their Google passwords" (support
   has verified this) - users should be directed to our internal password
   change/reset page

Problem:

   - When a Google account is flagged as "Require password change: On"
   the password change is NOT redirected, and process as a Google Password
   change

Sub-Problem:

   - When an account is flagged by Google's automatic process for
   compromise (eg. "Leaked Password") the wording of the message states: "This
   Leaked password alert is to inform you that Google has suspended an account
   in your domain due to a potentially leaked password." but this isn't the
   case - the account isn't suspended - it is set as "Require password change"



I am hoping that we can either get the behaviour changed - or get the
documentation updated to reflect reality.



Frank
