**The UnsupportedSettingsException in AWS Directory Service: A Comprehensive Guide**
When working with AWS Directory Service, you may encounter various exceptions that help pinpoint and handle any issues with your directory configuration. One such common exception is the UnsupportedSettingsException. In this article, we will delve deep into this exception, understand its causes, and explore potential solutions.
Understanding the UnsupportedSettingsException
The com.amazonaws.services.directory.model.UnsupportedSettingsException is thrown when attempting to create or modify a directory with unsupported configuration settings. This exception helps enforce valid inputs and maintain the integrity of your AWS Directory Service.
Let’s take a closer look at the structure and key properties of this exception in Java:

public class UnsupportedSettingsException extends com.amazonaws.AmazonServiceException {
private static final long serialVersionUID = 1L;
private java.util.List<String> unsupportedSettings;
/**
* Returns the unsupported configuration settings associated with the exception.
*
* @return List of unsupported configuration settings
*/
public java.util.List<String> getUnsupportedSettings() {
return unsupportedSettings;
}
}
Causes of the UnsupportedSettingsException
The UnsupportedSettingsException can occur due to several reasons. Here are a few scenarios where this exception might be thrown:
1. Unsupported Directory Type
AWS Directory Service supports multiple directory types, such as Simple AD, Microsoft AD, and AD Connector. Each directory type has its list of supported configuration settings. If you attempt to configure unsupported settings for a specific directory type, the UnsupportedSettingsException will be raised.
For example, when creating a Microsoft AD directory, the following settings may be considered unsupported:
1
2
3
4
5
6
CreateDirectoryRequest request = new CreateDirectoryRequest()
.withName("myDirectory")
.withDirectoryType(DirectoryType.MicrosoftAD)
.withShortName("mysubdomain")
.withPassword("myPassword")
.withUnsupportedSettings("UnsupportedSetting1", "UnsupportedSetting2");
2. Invalid Directory Size
AWS Directory Service offers directory size options, such as Small, Large, and ExtraLarge. Each directory size has specific resource allocations, including CPU, memory, and storage. If you specify an unsupported or invalid directory size, the UnsupportedSettingsException will be thrown.
For instance, the following code will trigger the exception due to the use of an invalid directory size:
1
2
3
4
5
CreateDirectoryRequest request = new CreateDirectoryRequest()
.withName("myDirectory")
.withDirectoryType(DirectoryType.SimpleAD)
.withPassword("myPassword")
.withSize("UnsupportedSize");
3. Unsupported Advanced Security Mode
AWS Directory Service offers an advanced security mode for Microsoft AD directories. When enabling advanced security, you can choose either ENABLED or DISABLED. If you attempt to set an unsupported value for the advanced security mode, the UnsupportedSettingsException will be raised.
Here’s an example that demonstrates an unsupported advanced security mode:
1
2
3
4
5
UpdateConditionalForwarderRequest request = new UpdateConditionalForwarderRequest()
.withDirectoryId("myDirectoryId")
.withRemoteDomainName("example.com")
.withDnsIpAddrs("192.0.2.1", "192.0.2.2")
.withunSupportedAdvancedSecurityMode("AnyValue");
Handling the UnsupportedSettingsException
To handle the UnsupportedSettingsException gracefully, you can make use of exception handling techniques. When catching this exception, you can log the specific error details, display user-friendly messages, or even revert to default settings.
Here’s an example of catching and handling the UnsupportedSettingsException in Java:
1

try {
CreateDirectoryResult result = directoryService.createDirectory(request);
// Directory creation successful
} catch (UnsupportedSettingsException ex) {
List<String> unsupportedSettings = ex.getUnsupportedSettings();
// Log the unsupported settings or display a user-friendly error message
}
It is crucial to understand the specific unsupported settings associated with the exception to take appropriate action.
Conclusion
The UnsupportedSettingsException in AWS Directory Service helps maintain consistency and safeguards the configuration of your directories. By throwing this exception, AWS ensures that only supported settings and valid inputs are used.
