Configuring LTPA in Docker or Podman

This topic includes the steps to configure LTPA keys on Docker.

Update the .env file to reflect the following attributes and values.
```
ENABLE_LTPA=true
LTPA_KEYS_FILE_PATH=key\_file\_path
LTPA_KEYS=/ltpa-config/ltpa.keys
LTPA_KEYS_PASSWORD=liberty\_server\_password
LTPA_DURATION_MINUTES=minutes\_token\_valid
```
The value for key_file_path must be the absolute path to the file. For example, if keys are in the ltpa.key file and in the /opt/hcl/sametime directory.
```
LTPA_KEYS_FILE_PATH=/opt/hcl/sametime/ltpa.keys
```
The value of LTPA_DURATION_MINUTES must be the same as the value for the Domino web SSO token expiration.
Update the custom.env file to include the following.
```
STI__ST_BB_NAMES__ST_AUTH_TOKEN=Fork:Jwt,Ltpa
```
Update the docker-compose.yml file to include the following.
```
SAMETIME_EXTERNAL_WARINTEGRATION=true
```
Optional: If integrating with Connections and using a realm, add the realm name to the .env. For more information on integrating with Connections, see Integrating with HCL Connections.
```
LTPA_REALM=<realmname>
```
