To set up LTPA security, configure settings to match on
both the Content Platform Engine application
server and the Application Engine application
server. If your Application Engine and Content Platform Engine are on the same WebSphere® Application
Server, you are not required to
configure LTPA.
About this task
Important: In a highly available
WebSphere environment where
Content Platform Engine and
Application Engine are managed by different
deployment managers, perform any LTPA configuration steps on the administrative
server only. The scope of this action will affect the entire application
server configuration.
If you are already using LTPA with
your Content Platform Engine application
server, you must export only the existing keys and copy the key file
to the Application Engine server.
Check with your Content Platform Engine administrator.
To
configure LTPA:
Procedure
- On the Content Platform Engine server,
log in to the WebSphere administrative
console.
- Navigate to the LTPA settings page at and select LTPA from
the right side of the panel.
- Enter
a value for the LTPA timeout that is larger
than the default. For example, if the timeout value is
left at the default value of 120 minutes, the LTPA key expires after
2 hours. Users will not be able to log in to Workplace after being logged in
for 2 hours.
Important: In high availability environments, set the timeout
value for forwarded credentials between servers:

- Save your changes.
- In the box for Cross-cell single sign-on,
type a password to create the LTPA password.
For password restrictions, see the WebSphere Application
Server documentation. If you have
already configured Content Platform Engine for
LTPA, use the existing password in the Application Engine configuration.
- Enter the fully qualified path for the Key File
Name. For example, /opt/LTPA/ltpa_key_name.
- Click Export keys. Verify
that a message like the following message is displayed: The keys were
successfully exported to the file ltpa_key_name.
- Click OK, then click Save
changes directly to the master configuration.
- Stop
and restart the WebSphere Application
Server instance.
- Copy the key file from the Content Platform Engine server location you
specified to a directory on the Application Engine server. For example, /opt/LTPA/ltpa_key_name
- On the Application Engine server,
log in to the WebSphere administrative
console.
- Navigate to the LTPA settings page at and select LTPA from
the right side of the panel.
- Enter a value for the LTPA timeout that
is larger than the default. For example, if the timeout
value is left at the default value of 120 minutes, the LTPA key expires
after 2 hours. Users will not be able to log in to Workplace after being logged in
for 2 hours.
Note: In high availability environments,
set the timeout to
60,000.
- Save your changes.
- In the box for Cross-cell single sign-on,
type and confirm the LTPA password you created
for Content Platform Engine.
For
password restrictions, see the WebSphere Application
Server documentation.
If you have already configured Content Platform Engine for LTPA, use the existing
password in the Application Engine configuration.
- Specify the path for the key file that you copied to the Application Engine server. For
example, /opt/LTPA/ltpa_key_name.
- Click Import keys. Verify
that a message like the following one is displayed: The keys were
successfully imported from the file ltpa_key_name.
- Save your changes.
In
a highly available environment, synchronize the changes across all
nodes after saving your configuration settings.
