Clicking login redirects to Microsoft login page unless I open a private window.

It redirects to https://login.microsoftonline.com. But login in there doesn't work.
I use firefox.

Hello all, 

The fix of the login issue has been implemented. Let us know if all is fine or you still face the issues.

If the redirection still occurs to Microsoft login, let us know by adding a screenshot where we can see the timestamp of the action.

Thanks a lot, 
Lina

Hello @unsigned_char_array 

Thanks for reporting this. We've got a couple of similar reports on this and are investigating the issue. 

Can you try to clear your browsing history and try the login? 

For anyone else, facing similar issue, report it here or drop us an email at community@st.com.

Let me know if it helps. 

Thanks,
Lina

It's on my work PC and I don't want to log out everywhere and lose history.

Edit. At my home PC I have the problem too. I need to use a private tab.

Both PCs use firefox.

Getting the same thing here. Private window in Edge and Opera does the same thing. Private window in Chrome finally allows me to login normally. Happened yesterday too.

Fewer questions here than normal on a Monday morning.

ST should really look into getting a proper forum support software. This one is embarrassing at times. Logging in should just work.

I reported this to Lina last Friday (27-June), not on the site, because I couldn't log in.

Initially from Chrome on an Android, subsequently on Chrome on PC's. I had to clear the cookies/history, but wasn't clear why it was redirecting this way to ST's Active Directory, which didn't succeed because I am not a member of their domain.

But this login does not work. I have to open an incognito tab or clear my cookies in order to login to the forums.

For me the 'federated logon' still pops out when I begin logged-out and click on the "black head" icon on any forum page. I've logged on from the main st.com page, then browsed to the community. I guess this happens to people with Edge browser and email addresses associated with Microsoft.

Update:

Because of the comment of @Pavel A. I got curious. I discovered the following behavior:

  • yesterday I could not log in, because it forced microsoft login and microsoft login failed, only login in via private window in firefox worked
  • this morning I could log in the normal way
  • after Pavel's comment I tried the following
  • I logged out and could log back in the normal way 
  • then I logged in on answers.microsoft.com with the same email
  • logging out on st and logging back in now fails. It forces the microsoft login. So I suspected it sees I'm logged in to microsoft with the same email
  • I logged out of microsoft. Trying to log in on st fails and forces microsoft login. This is odd to me.
  • I tried to use a private window. but this time logging in failed in the private window too!
  • It does work in Chrome's incognito.

I think like something is stored on the server site, because a new private window should not have retained cookies.

Edit:

after waiting a certain time it does work again...
Edit2:
after a longer wait it fails again. Also sometimes fails in Chrome incognito. Seems very inconsistent.

Hi,

I just tried to login on my Linux PC again --

Surprise: login same as last week, working as usual.

So... difficult, to say, what happened or someone changed on the login procedure.

I get this with Edge or Firefox, opening a private window in Firefox allowed me to login.

I also had the stated problems of signing in to community.st.com (i.e., getting redirected to Microsoft Live Single-Signon for tenant STMicroelectronics), despite having no problems with signing in or being automatically signed in on other STMicroelectronics SSO-based web properties (e.g., www.st.com , ols.st.com etc.)

I fixed the issue in the following way:

On community.st.com pages, the footer includes a "Manage cookies" link. Clicking on it pops up a onetrust-based "Privacy Preference Center". As I had previously (days ago) declined all cookies in the first-visit cookie banner, in this popup now I was given a "Allow All" button as an action option. After and since clicking this button, I'm able to sign in: i.e. clicking "Sign in to post" no longer brings me to the Microsoft tenant sig-nin page, but to the sign-in page over at my.st.com.

Of course this issue still needs to get resolved from ST's side, as it shall be possible (GDPR) to use community.st.com without consenting to onetrust's privacy-intrusive behavior (which includes sharing data to third-party "advertising partners").

Can you share the "manage cookies" link? In Firefox and Brave the "link" is not clickable. It's just underlined text. The other texts are clickable links.

The "Manage cookies" link does not have a URL; clicking it triggers a popup via JavaScript on the same page that you are currently viewing.

Make sure that JavaScript is enabled.

Also, active adblockers such as Ghostery and AdBlock may or may not cause issues here, e.g. Ghostery identifies the OneTrust Consent Manager and blocks it iff Ghostery is active. I have all my adblockers deactivated for community.st.com.
