Configuring Session Timeout - dogtagpki/pki GitHub Wiki
The Session Timeout configuration affects how long an idle PKI Console will remain connected to the server. For some, the default 5 minutes timeout might be too short.
The session timeout can be configured during installation (see Two-Step Installation) or after installation.
To configure the session timeout, edit the keepAliveTimeout parameter in /var/lib/pki/pki-tomcat/conf/server.xml:
<Server>
<Service>
<Connector name="Secure"
...
keepAliveTimeout="300000"
...
/>
</Service>
</Server>
