Captive portal / Authentification tab not closing automatically on Chrome & Brave

Hello everyone,

 

We are currently experimenting outbound firewall authentication with Azure AD as a SAML IdP. Here is the cookbook :

https://docs.fortinet.com/document/fortigate/7.4.1/administration-guide/33053/outbound-firewall-auth... 

 

Everything is working fine but we have strange issue with Google Chrome and Brave. After the user athentication, the user get stuck on this page and he's not redirected to the original request / URL like it did on Firefox and Edge for example.

 

Chrome :

Brave :

As you can see, the user get stuck on the exact same URL, blank page and the TAB is not closing : https://login.microsoftonline.com/common/SAS/ProcessAuth

 

For us it's not a big deal, you close this TAB and firewall rules are well applies based on your Azure AD dynamic(s) group(s). But, we already know that it will be a big issue for our users...

 

We have check multiple settings but everything seems fine... Am I missing something or it's a bug comming from Chrome and Brave ?

 

Regards,

Louis
