We have SharePoint Farm, the logins are provided by ADFS 3.0, on ADFS one of Identity provider is Azure ACS, the Azure ACS has been retired, now we need connect Azure AD B2C with ADFS to provide Social accounts authentications.
Where we can find metadata file for SAML or WS-Fed in Azure AD B2C connect to ADFS or alternatives to do the connection.

Social Accounts -> Azue AD B2C -> ADFS -> SP2016

    anonymous user MiguelGonalves-0314,

    1. You need to first implement https://v4.hkg1.meaqua.org/en-us/azure/active-directory-b2c/connect-with-saml-service-providers in your B2C tenant.
    2. Add a claims provider in ADFS by specifying metadata URL: https://tenant-name.b2clogin.com/tenant-name.onmicrosoft.com/policy-name/Samlp/metadata
    3. Create a custom claim rule on the B2C claims provider in ADFS to pass all claims sent by B2C: c:[]
      => issue(claim = c);
    4. Update your signup_signin.xml file with below parameters. Replace the URL under metadata tag with your ADFS Server's metadata url. 5471-capture.jpg

    Note : If you face any errors on ADFS page, review ADFS Admin event logs.
