About this task
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.
