Work with LTPA properties files

Use properties files to modify or delete Lightweight Third Party Authentication (LTPA) properties.

Determine the changes to make to your LTPA configuration.

Start the wsadmin scripting tool. To start wsadmin using the Jython language, run the wsadmin -lang jython command from the bin directory of the server profile.

Use a properties file to modify or delete a LTPA object.

Run administrative commands using wsadmin to change a properties file for a LTPA object, validate the properties, and apply them to the configuration.

Action	Procedure
create	Not applicable
modify	Edit property values in the LTPA properties file and then run the applyConfigProperties command.
delete	Run the deleteConfigProperties command to delete one or more properties. If a deleted property has a default value, the property is set to the default value. Otherwise, the deleted property is removed.
create Property	Not applicable
delete Property	Not applicable

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

Tasks

• Modify an existing properties file.
  1. Obtain a properties file for the LTPA object to change.

     We can extract a properties file for an LTPA object using the extractConfigProperties command.

  2. Open the properties file in an editor and change the properties as needed.

     Ensure that the environment variables in the properties file match the system. To specify a custom property, edit the AttributeInfo value and properties values. An example LTPA properties file follows:

     #
     # Header 
     #
     ResourceType=LTPA
     ImplementingResourceType=Security
     ResourceId=Cell=!{cellName}:Security=:LTPA=
     #
     
     #
     #Properties
     #
     simpleAuthConfig=system.LTPA
     keySetGroup=CellLTPAKeySetGroup #ObjectName(KeySetGroup)
     authContextImplClass=com.ibm.ISecurityLocalObjectTokenBaseImpl.WSSecurityContextLTPAImpl
     authConfig=system.LTPA
     isCredentialForwardable=false #boolean,default(false)
     timeout=120 #long,required,default(0)
     OID="oid:1.3.18.0.2.30.2"
     password=null #required
     authValidationConfig=system.LTPA
     
     
     #
     # Header SingleSignon Section
     #
     ResourceType=SingleSignon
     ImplementingResourceType=Security
     ResourceId=Cell=!{cellName}:Security=:LTPA=:SingleSignon=
     AttributeInfo=singleSignon
     #
     
     #
     #Properties
     #
     enabled=true #boolean,default(false)
     domainName=
     requiresSSL=false #boolean,default(false)
     
     
     EnvironmentVariablesSection
     #Environment Variables
     cellName=myCell
     

  3. Run the applyConfigProperties command to create or change an LTPA object.

     Running the applyConfigProperties command applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:

     AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt'])
     

• If we no longer need a property, we can delete the LTPA property.

  To delete one or more properties, specify only the properties to be deleted in the properties file and then run the deleteConfigProperties command; for example:

  AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]') 
  

Use the properties file to configure and manage the LTPA properties.

What to do next
