Openid identity provider in Azure AD B2C
While configuring openid identity provider in Azure AD B2C, need to get a better view of using either 'query' or 'form_post' in the 'Response mode' attribute.
Does it make any difference with regards storing different fields, which are part of claims from the identity provider, as user attributes in azure AD B2C.
I tried setting up identity provider using both 'query' and 'form_post'
When using 'query' - when a new user signs-up and is added to B2C tenant, I am unable to find the users identifier that was passed in the claim by identity provider, in any of the attributes for the user.
When using 'form_post' - when a new user signs-up and is added to B2C tenant, I am able to find the users identifier that was passed in the claim by identity provider, in any of the attributes for the user.
In both instances, I have access user attributes using graph.
Are my above observations correct or there is something I am doing wrong?
Thanks in advance.
