sl=20

esac

now, i have one user named insp wich can open till 20 sessions and onether 30 users wich username starts from "dist1" and goes to "dist30".
my problem is when "dist1" logs in , and then "dist11" or "dist12" trys to login, thay can't login. The script should limit every user to one session , but what happens is that when "dist1" logs in , then "dist11" can't , and when "dist2" logs in , "dist21" can't login anymore. it's not assuming a diference between "dist1" and "dist11" or "dist2" and "dist21".
Can someone help me to undestand what's wrong?
many thanks

systemd-logind.service

SYSTEMD-LOGIND.SERVICE(8)				      systemd-logind.service					 SYSTEMD-LOGIND.SERVICE(8)

NAME

       systemd-logind.service, systemd-logind - Login manager

SYNOPSIS

       systemd-logind.service

       /lib/systemd/systemd-logind

DESCRIPTION

       systemd-logind is a system service that manages user logins. It is responsible for:

       o   Keeping track of users and sessions, their processes and their idle state. This is implemented by allocating a systemd slice unit for
	   each user below user.slice, and a scope unit below it for each concurrent session of a user. Also, a per-user service manager is
	   started as system service instance of user@.service for each logged in user.

       o   Generating and managing session IDs. If auditing is available and an audit session ID is already set for a session, then this ID is
	   reused as the session ID. Otherwise, an independent session counter is used.

       o   Providing PolicyKit-based access for users for operations such as system shutdown or sleep

       o   Implementing a shutdown/sleep inhibition logic for applications

       o   Handling of power/sleep hardware keys

       o   Multi-seat management

       o   Session switch management

       o   Device access management for users

       o   Automatic spawning of text logins (gettys) on virtual console activation and user runtime directory management

       User sessions are registered with logind via the pam_systemd(8) PAM module.

       See logind.conf(5) for information about the configuration of this service.

       See sd-login(3) for information about the basic concepts of logind such as users, sessions and seats.

       See the logind D-Bus API Documentation[1] for information about the APIs systemd-logind provides.

       For more information on the inhibition logic see the Inhibitor Lock Developer Documentation[2].
