public abstract class IdentityMapper
extends java.lang.Object
implements UnboundIDExtension, Reconfigurable<IdentityMapperConfig>, ExampleUsageProvider

This class defines an API that must be implemented by extensions which attempt to map a username to a user defined in the server. This is generally used when processing an authorization ID, as might be provided when performing SASL authentication or in a control like the proxied authorization or intermediate client controls. In order for the mapping to be established, the identity mapper must locate exactly one entry in the server corresponding to the provided username. If no entries are found, or if multiple entries are found, then the mapping attempt must fail.

Configuring Identity Mappers

In order to configure an identity mapper created using this API, use a command like:

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

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

Constructor Detail

IdentityMapper

public IdentityMapper()

Creates a new instance of this identity mapper. All identity mapper implementations must include a default constructor, but any initialization should generally be done in the initializeIdentityMapper 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(com.unboundid.util.args.ArgumentParser parser)
                           throws com.unboundid.util.args.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:

com.unboundid.util.args.ArgumentException - If a problem is encountered while updating the provided argument parser.

initializeIdentityMapper

public void initializeIdentityMapper(DirectoryServerContext serverContext,
                                     IdentityMapperConfig config,
                                     com.unboundid.util.args.ArgumentParser parser)
                              throws com.unboundid.ldap.sdk.LDAPException

Initializes this identity mapper.

Parameters:

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

config - The general configuration for this identity mapper.

parser - The argument parser which has been initialized from the configuration for this identity mapper.

Throws:

com.unboundid.ldap.sdk.LDAPException - If a problem occurs while initializing this identity mapper.

isConfigurationAcceptable

public boolean isConfigurationAcceptable(IdentityMapperConfig config,
                                         com.unboundid.util.args.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<IdentityMapperConfig>

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 com.unboundid.ldap.sdk.ResultCode applyConfiguration(IdentityMapperConfig config,
                                                            com.unboundid.util.args.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<IdentityMapperConfig>

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.

finalizeIdentityMapper

public void finalizeIdentityMapper()

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

mapUsername

public abstract java.lang.String mapUsername(java.lang.String username)
                                      throws com.unboundid.ldap.sdk.LDAPException

Performs any processing which may be necessary to map the provided username to a user within the server.

Parameters:

username - The username to be mapped to a user within the server.

Returns:

The DN of the user within the server to which the provided username corresponds.

Throws:

com.unboundid.ldap.sdk.LDAPException - If the provided username cannot be mapped to exactly one user in the server.

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.
