title: LDAP vs ADFS Single Sign On
body: <p>I work for a company that offers a SaaS solution.  We currently allow customers to SSO in using ADFS on their side and we are the Service Provider accepting a SAML assertion.  We seem to get a large number of people requesting SSO via LDAP though.  I understand that LDAP is the protocol to authenticate users on an AD network.  I'm wondering - is this synonymous with ADFS or are they talking about something else?  </p>
  
  <p>If ADFS isn't necessarily the best practice for LDAP authentication over the internet, could someone give me a high level explanation on how we would authenticate against another website using LDAP?</p>
