About this task
Step 3 towards the goal:
Configuring LTPA and working with keys
Procedure
To support single sign-on (SSO) in WebSphere® Application
Server across multiple WebSphere Application
Server domains or cells, you must share the LTPA keys and the password
among the domains. You can import LTPA keys from other domains and
export keys to other domains. Note: You should disable
automatic key generation if you import or export keys to or from another
cell. This disabling causes the imported keys to get lost and the
exported keys to no longer interoperate with this cell over time
You
must recycle the node agents and application servers to accept the
new keys. If any of the node agents are down, run a manual file synchronization
utility from the node agent machine to synchronize the security configuration
from the deployment manager.
