Accessing Zoho via ADFS using SAML

Active Directory Federation Services( ADFS ) is a Single Sign On solution created by Microsoft. ADFS manages authentication through a proxy service hosted between Active Directory (AD) and the target application. You must obtain the login URL, logout URL and the certificate from ADFS.
  1. Log in to the ADFS 3.0 server and open the management console.
  2. Right-click Service in the left-pane menu and choose Edit Federation Service Properties.
  3. Under General, make sure that your DNS entries and certificate names are correct.
  4. Using your Federation Service name, use a browser and go to  https://federationservicename.com/federationMetaData/2007-06/FederationMetaData.xml
    Example:
    https://yourdomain.samlportal.com/federationMetaData/2007-06/FederationMetaData.xml
    The login URL and logout URL are present in the XML file as SingleSignOnService and SingleLogoutService tags
  5. Export the Token-Signing certificate:
    1. Right-click Certificate in the left-pane menu and click View Certificate.

    2. Select the Details tab.
