| <p>A client is authenticated when it connects with valid credentials to a Geode cache server that is configured with the client authentication callback. |
| For details on the server’s role in authentication and what it expects from the client, see <a href="geodeman/managing/security/implementing_authentication.html">Implementing Authentication</a> in the <em>Geode User Guide</em>.</p> |
| |
| <p>In your application, authentication credentials must be set when creating the cache. In practice, |
| this means setting the authentication credentials when you create the CacheFactory.</p> |
| |
| <h3 id=".net-authentication-example">.NET Authentication Example</h3> |
| |
| <p>The following excerpt is taken from the .NET example provided with your Native Client distribution in the <code>../examples/dotnet/authinitialize</code> directory.</p> |
| |
| <p>In this C# authentication example, the <code>CacheFactory</code> creation process sets the authentication callback:</p> |
| <pre class="highlight csharp"><code> <span class="kt">var</span> <span class="n">cacheFactory</span> <span class="p">=</span> <span class="k">new</span> <span class="nf">CacheFactory</span><span class="p">()</span> |
| <span class="p">.</span><span class="nf">Set</span><span class="p">(</span><span class="s">"log-level"</span><span class="p">,</span> <span class="s">"none"</span><span class="p">)</span> |
| <span class="p">.</span><span class="nf">SetAuthInitialize</span><span class="p">(</span><span class="k">new</span> <span class="nf">ExampleAuthInitialize</span><span class="p">());</span> |
| </code></pre> |
| |
| <p>Credentials are implemented in the <code>GetCredentials</code> member function of the <code>ExampleAuthInitialize</code> class, which implements the <code>IAuthInitialize</code> interface:</p> |
| <pre class="highlight csharp"><code> <span class="k">class</span> <span class="nc">ExampleAuthInitialize</span> <span class="p">:</span> <span class="n">IAuthInitialize</span> |
