The index.html under host:port/uri/samples displays:
1. Authentication Samples 2. ID-FF Sample 3. SAMLv2 Sample 4. Multi-Federation Protocols Sample
However, the following link to the policy samples is missing in index.html: host:port/uri/samples/policy/policy-plugins.html
Workaround: Open the host:port/uri/samples/policy/policy-plugins.html file in your browser.
