| A client is authenticated when it connects with valid credentials to a <%=vars.product_name%> 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 [Implementing Authentication](geodeman/managing/security/implementing_authentication.html) in the *<%=vars.product_name%> User Guide*. |
| |
| 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. |
| |
| ### C++ Authentication Example |
| |
| In this C++ authentication example, the `CacheFactory` creation process sets the authentication callback: |
| |
| ```cpp |
| auto cache = CacheFactory() |
| .set("log-level", "none") |
| .setAuthInitialize(std::unique_ptr<ExampleAuthInitialize>(new ExampleAuthInitialize())) |
| .create(); |
| ``` |
| |
| Credentials are implemented in the `getCredentials` member function of the `ExampleAuthInitialize`, which is derived from the `AuthInitialize` abstract class. |
| |
| ```cpp |
| std::shared_ptr<Properties> ExampleAuthInitialize::getCredentials( |
| const std::shared_ptr<Properties>& securityprops, |
| const std::string& /*server*/) { |
| |
| securityprops->insert("security-username", "root"); |
| securityprops->insert("security-password", "root"); |
| |
| return securityprops; |
| } |
| ``` |
