| 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. |
| |
| ### .NET Authentication Example |
| |
| The following excerpt is taken from the .NET example provided with your Native Client distribution in the `../examples/dotnet/authinitialize` directory. |
| |
| In this C# authentication example, the `CacheFactory` creation process sets the authentication callback: |
| |
| ```cs |
| var cacheFactory = new CacheFactory() |
| .Set("log-level", "none") |
| .SetAuthInitialize(new ExampleAuthInitialize()); |
| ``` |
| |
| Credentials are implemented in the `GetCredentials` member function of the `ExampleAuthInitialize` class, which implements the `IAuthInitialize` interface: |
| |
| ```cs |
| class ExampleAuthInitialize : IAuthInitialize |
| { |
| public ExampleAuthInitialize() |
| { |
| // TODO initialize your resources here |
| Console.Out.WriteLine("ExampleAuthInitialize::ExampleAuthInitialize called"); |
| } |
| |
| public void Close() |
| { |
| // TODO close your resources here |
| Console.Out.WriteLine("ExampleAuthInitialize::Close called"); |
| } |
| |
| public Properties<string, object> GetCredentials(Properties<string, string> props, string server) |
| { |
| // TODO get your username and password |
| Console.Out.WriteLine("ExampleAuthInitialize::GetCredentials called"); |
| |
| var credentials = new Properties<string, object>(); |
| credentials.Insert("security-username", "root"); |
| credentials.Insert("security-password", "root"); |
| return credentials; |
| } |
| } |
| |
| ``` |
