Activating Lightweight Third Party Authentication key versions

 

Key sets manage Lightweight Third Party Authentication (LTPA) keys in a key store that is based on a key alias prefix. A key alias prefix is automatically generated when you generate a new key and store it in a key store. Key stores can contain multiple versions of keys for any given key alias prefix. You can specify a maximum number of active keys in the key set configuration. You must know the name of the key set group and the management scope where the key set group is defined.

The default key set group is CellLTPAKeySetGroup. Complete the following steps in the administrative console.

 

Overview

LTPA keys are used to encrypt the LTPA token. You might want to set a specific number of active keys that WebSphere Application Server returns when the server queries for keys for a particular key set. The following steps are needed to complete this task in the administrative console.

 

Procedure

  1. Click Security > SSL certificate and key management > Manage endpoint security configurations.

  2. Expand the tree to the inbound or outbound management scope that contains the key set group, and then click the scope link.

  3. Under Related Items, click Key Sets.

  4. Click the key set that you want to modify.

  5. In the Maximum number of keys referenced field, type a numerical value for the maximum number of keys that you want to activate.

  6. Click OK and Save to save the changes to the master configuration.

  7. Start the server again for the changes to become active. WebSphere Application Server activates only the number of recent keys that you specified.

 

Results

The Maximum number of keys referenced value determines how many active keys are returned when the server queries for keys for the selected key set.

 

What to do next

You can click Active key history in the Key set panel to display the keys that are active for this key set.
