[Bug]: variable LEAN_SESSION_EXPIRATION is not utilized by the app

[ilias-sp]

What is your set up?

Self Hosted Server

Version

3.3.2

Describe the issue

Variable that is meant to control the session duration is not used in the application.

[user@41 LEAN] > grep -Ri LEAN_SESSION_EXPIRATION *
config/sample.env:LEAN_SESSION_EXPIRATION = 28800                    # How many seconds after inactivity should we logout?  28800seconds = 8hours
[user@41 LEAN] > 

i believe that the file that should be consuming this variable is app/Core/Configuration/laravelConfig.php , that currently contains the below block:

        /*
        |--------------------------------------------------------------------------
        | Session Lifetime
        |--------------------------------------------------------------------------
        |
        | Here you may specify the number of minutes that you wish the session
        | to be allowed to remain idle before it expires. If you want them
        | to immediately expire on the browser closing, set that option.
        |
        */

        'lifetime' => 480, //8 hours

        'expire_on_close' => false,

        /*

Reproduction steps

Not Applicable

Additional Notes

i suppose above file should be modified from:

'lifetime' => 480, //8 hours

to:

'lifetime' => env('LEAN_SESSION_EXPIRATION', 480)
