public abstract class PasswordGenerator
extends java.lang.Object
implements UnboundIDExtension, Reconfigurable<PasswordGeneratorConfig>, ExampleUsageProvider

This class defines an API that must be implemented by extensions which generate user passwords. This is primarily used when processing a password modify extended operation in order to generate a new password for the target user if the request did not explicitly provide the new password that should be used. The generated password will not be subject to the constraints of any defined password validators.

Configuring Password Generators

In order to configure a password generator created using this API, use a command like:

      dsconfig create-password-generator \
           --generator-name "{generator-name}" \
           --type third-party \
           --set enabled:true \
           --set "extension-class:{class-name}" \
           --set "extension-argument:{name=value}"
 

where "{generator-name}" is the name to use for the password generator instance, "{class-name}" is the fully-qualified name of the Java class that extends com.unboundid.directory.sdk.ds.api.PasswordGenerator, and "{name=value}" represents name-value pairs for any arguments to provide to the password generator. If multiple arguments should be provided to the password generator, then the "--set extension-argument:{name=value}" option should be provided multiple times.

Constructor Detail

PasswordGenerator

public PasswordGenerator()

Creates a new instance of this password generator. All password generator implementations must include a default constructor, but any initialization should generally be done in the initializePasswordGenerator method.

Method Detail

getExtensionName

public abstract java.lang.String getExtensionName()

Retrieves a human-readable name for this extension.

Specified by:

getExtensionName in interface UnboundIDExtension

Returns:

A human-readable name for this extension.

getExtensionDescription

public abstract java.lang.String[] getExtensionDescription()

Retrieves a human-readable description for this extension. Each element of the array that is returned will be considered a separate paragraph in generated documentation.

Specified by:

getExtensionDescription in interface UnboundIDExtension

Returns:

A human-readable description for this extension, or null or an empty array if no description should be available.

defineConfigArguments

public void defineConfigArguments(ArgumentParser parser)
                           throws ArgumentException

Updates the provided argument parser to define any configuration arguments which may be used by this extension. The argument parser may also be updated to define relationships between arguments (e.g., to specify required, exclusive, or dependent argument sets).

Specified by:

defineConfigArguments in interface Configurable

Parameters:

parser - The argument parser to be updated with the configuration arguments which may be used by this extension.

Throws:

ArgumentException - If a problem is encountered while updating the provided argument parser.

initializePasswordGenerator

public void initializePasswordGenerator(DirectoryServerContext serverContext,
                                        PasswordGeneratorConfig config,
                                        ArgumentParser parser)
                                 throws LDAPException

Initializes this password generator.

Parameters:

serverContext - A handle to the server context for the server in which this extension is running.

config - The general configuration for this password generator.

parser - The argument parser which has been initialized from the configuration for this password generator.

Throws:

LDAPException - If a problem occurs while initializing this password generator.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(PasswordGeneratorConfig config,
                                         ArgumentParser parser,
                                         java.util.List<java.lang.String> unacceptableReasons)

Indicates whether the configuration represented by the provided argument parser is acceptable for use by this extension. The parser will have been used to parse any configuration available for this extension, and any automatic validation will have been performed. This method may be used to perform any more complex validation which cannot be performed automatically by the argument parser.

Specified by:

isConfigurationAcceptable in interface Reconfigurable<PasswordGeneratorConfig>

Parameters:

config - The general configuration for this extension.

parser - The argument parser that has been used to parse the proposed configuration for this extension.

unacceptableReasons - A list to which messages may be added to provide additional information about why the provided configuration is not acceptable.

Returns:

true if the configuration in the provided argument parser appears to be acceptable, or false if not.

applyConfiguration

public ResultCode applyConfiguration(PasswordGeneratorConfig config,
                                     ArgumentParser parser,
                                     java.util.List<java.lang.String> adminActionsRequired,
                                     java.util.List<java.lang.String> messages)

Attempts to apply the configuration from the provided argument parser to this extension.

Specified by:

applyConfiguration in interface Reconfigurable<PasswordGeneratorConfig>

Parameters:

config - The general configuration for this extension.

parser - The argument parser that has been used to parse the new configuration for this extension.

adminActionsRequired - A list to which messages may be added to provide additional information about any additional administrative actions that may be required to apply some of the configuration changes.

messages - A list to which messages may be added to provide additional information about the processing performed by this method.

Returns:

A result code providing information about the result of applying the configuration change. A result of SUCCESS should be used to indicate that all processing completed successfully. Any other result will indicate that a problem occurred during processing.

finalizePasswordGenerator

public void finalizePasswordGenerator()

Performs any cleanup which may be necessary when this password generator is to be taken out of service.

generatePassword

public abstract ByteString generatePassword(Entry userEntry)
                                     throws LDAPException

Performs any processing which may be necessary to generate a user password.

Parameters:

userEntry - The entry of the user for whom to generate the password.

Returns:

The generated password.

Throws:

LDAPException - If a problem occurs while attempting to generate a password for the user.

getExamplesArgumentSets

public java.util.Map<java.util.List<java.lang.String>,java.lang.String> getExamplesArgumentSets()

Retrieves a map containing examples of configurations that may be used for this extension. The map key should be a list of sample arguments, and the corresponding value should be a description of the behavior that will be exhibited by the extension when used with that configuration.

Specified by:

getExamplesArgumentSets in interface ExampleUsageProvider

Returns:

A map containing examples of configurations that may be used for this extension. It may be null or empty if there should not be any example argument sets.
