To support single sign-on (SSO) in WebSphere Application Server across multiple WAS domains or cells, share the LTPA keys and the password among the domains. We can import LTPA keys from other domains and export keys to other domains.
After you export LTPA keys from one cell, you must import these keys into another cell. If the other cell is on a separate system, you must FTP the key file in binary format. To import keys, you must know the password for the exported key file to access the LTPA keys. Verify that key files are exported from one of the cells into a file. Complete the following steps in the dmgr console to import key files for LTPA.
- Access the dmgr console for the cell that will receive the imported keys by typing http://server_name:port_number/ibm/console in a web browser.
- Click Security > Global security > Authentication mechanisms and expiration.
- Click LTPA.
- In the Password and Confirm password fields, enter the password used to decrypt the LTPA keys . This password must match the password that was used in the cell from which we are importing the keys.
- In the Fully qualified key file name field, specify the fully qualified path to the location where the signer keys reside. You must have write permission to this file.
- Click Import keys to import the keys to the location that you specified in the Fully qualified key file name field.
- Click OK and Save to save the changes to the master configuration. It is important to save the new set of keys to match the new password so that no problems are encountered when starting the servers later.
After a new set of keys is generated and saved, the generated keys are not used in the configuration until WAS is restarted.
After you enter the password in the Password and Confirm password fields and click Save, the password is not redisplayed on the dmgr console panel.
