How do you use SessionIdleTimeout in Identity Console 1.7.2?

I saw that Identity Console 1.7.2 has a new setting, SessionIdleTimeout.  Has anyone gotten it to work? The documentation here:

Doesn't show an example:

Configuring Session-timeout for Identity Console

The session-timeout value represents the amount of time users can leave a page unattended in their web browser. The application will logout when the set time is complete.

NOTE:Session-timeout by default set at 15 minutes, the user can change the value as per their requirement.

To set the session-timeout, perform the following actions:

  1. Login in to the Identity Console application server.

  2. Navigate to the /etc/opt/novell/eDirAPI/conf/ location.

  3. Open the edirapi.conf file in a text editor and add the property SessionIdleTimeout with appropriate value.

  4. Save the file and restart Identity Console.

I've tried putting it in with a value in quotes and without quotes.  Is it in minutes (I assume it is)?

The product is still mostly unusable, but this would help a lot.
