How to configure SSO using OAuth and OpenID connect for AD2BC for Azure ADB2C?

When you protect multiple apps with AAD B2C, SSO is enabled by default. There is no configuration needed. You can adjust the configuration of the SSO as seen here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/session-behavior

ReactJS app authentication and authorization with Azure AD with OpenID connect

I wanted to implement ReactJS application authentication with Azure AD with OpenID connect. Microsoft has provided MSAL2.0 library (MSAL React supports the authorization code flow) but is it based on OpenID connect protocol?
Thanks,
Mahesh
MSAL Standards compliant with OAuth v2.0 and OpenID Connect (OIDC).
When it comes to your scenario MSAL React uses the OAuth 2.0 Authorization Code Flow with PKCE (Proof Key for Code Exchange), providing additional security.
You can find more information here MSAL for React

SSO with Keycloak and Azure Active Directory

We have integrated keycloak with Azure Active Directory and integrated it with a few applications.
We have a few applications that are directly integrated with Azure Active Directory. Is there an approach I can follow to make a person logged in to one application to be signed in all the other applications irrespective of the authentication provider used (keycloak or Azure AD)?
Normally I'll be logged into all applications integrated with keycloak if I signin into one application integrated with keycloak and vice-versa with Azure AD.
Your requirement can be fulfilled with the app service feature by leveraging the token store and authorization behavior of the configured authentication providers for the apps configured. But only tokens received from keycloak can be forwarded to Azure AD for authentication purposes and further sign in respectively to all apps registered with Azure AD. The reverse is not possible as keycloak doesn’t has the ability to forward the sign in token request received for the application configured back to Azure AD for authorization.
You will have to enter the REST API code for signing in and out of a session accordingly by incorporating the below likewise code in your environment.
Log in with the Microsoft Identity Platform
Log in with Facebook
Log in with Google
Log in with Twitter
Log in with Apple
Please find the below documentation for an approach on forwarding the authentication tokens from Keycloak to Azure AD for access authorization: -

Azure B2B direct federation with Auth0 as IDP

Azure B2B gives simple steps for direct federation with google and facebook.Though, i don't see any documentation to establish direct federation with Auth0 or Okta. I tried myself with Auth0 at the time or invitation my user succesfully login with auth0 account but after redirection to invitation.microsoft.com getting redemtion failure.
Can someone give me steps to setup Auth0 as IDP and then configure that with Azure AD direct federation.
https://auth0.com/docs/protocols/saml-configuration-options/configure-auth0-as-saml-identity-provider
i have already setup everything as mentioned in above document but still not able to redeem invitation after login.
Any help would be highly appreciated!!!
Azure AD B2B can be configured to federate with identity providers that use the WS-Fed or SAML. There is no specific Document for direct federation either from OKTA or Azure. From Azure end Direct federation is only allowed for policies where the authentication URL’s domain matches the target domain, or where the authentication URL is one of these allowed identity providers as per this document. I recommend you to open a support case with Auth0 since it involves multiple parties.

Can we use OneLogin/Okta/Auth0 as Proxy SP between Google IdP and application

We have an application for which we would like to enable users to login into our application with their own Identity Providers like Google, ADFS etc with SAML 2.0 as protocol.
In this context our application will be SP and Identity Providers will be Google, ADFS.
But currently we don't have SAML implementation at our application, so we would like to use some platform like OneLogin/Okta/Auth0 as middle proxy between our application and IdP so that SAML related handling can be done at OneLogin/Okta/Auth0 and we need to get callback to our application with user details after success login.
Is this possible with any SASS based SAML providers? and how to do it.
Thanks in advance
Yes - connect to Auth0 / Okta via OpenID Connect and then connect the IDP to other IDP via SAML.
So in this context, Auth0 / Okta is a SAML SP.
Have a look here.
