App login expires

Sometimes the Rocket.Chat Apps require a new login. On Desktop and on mobile too.
Depends the App-Login period on the Setting “Account -> Login Expiration in days”?
Is there a way to set it to infinite? I can edit the setting to 999999999 - but does this solve the unwanted loggout?
We have some mobile users who can not change der ldap password.

The docs say: Login Expiration in Days: After this number of days of inactivity the user will be logged out.

I think the inactivity here is false - even active users get logged out.

I have the same problem!
