As shown in below screenshot, our web site supports two external SignIns: WeCom and Azure AD.
Some end users have both WeCom and Azure AD account, sometimes they login from WeCom, sometimes they are from Azure AD.
How to configure then the web site knows a user from WeCom and from Azure AD is actually same user, if they have same email address?
Would it be an option to have the portal only use Azure AD and add WeCom as extertnal identifier in Azure AD?
