Public bug reported:

We use Dell Optiplex 7010 machines in our student lab. These machines
are capable of suspending and resuming, so that we don't waste power
during the night. In our lab we also use LDAP authentication for the
students. The problem is that networking is disabled once the machine is
resumed after a suspend. Because of the LDAP authentication, networking
is required for authentication, thus we cannot login to the machine
after a suspend. A "work-around" to restart network-manager is therefor
not an option.

I have tried numerous things, 
* creating a file /etc/pm/config.d/network-resume with the content "SUSPEND_MODULE="e1000e"

Outcome: This seems to break the suspend functionality. When manually
entering "suspend" it goes directly to the lock screen. The networking
is still disabled, so I cannot log in.

* creating a file /etc/pm/sleep.d/network-resume with

 #!/bin/sh

case ${1} in
	resume|thaw)
	nmcli nm sleep false
		;;
esac

Outcome: Manually suspending works, resume only works when pressing the
power button. Once resumed the networking is still disabled, and thus I
cannot log in.

#!/bin/sh

case "${1}" in

                ;;
esac

Outcome: Manually suspending works, resume only works when pressing the
power button. Once resumed the networking is still disabled, and thus I
cannot log in. After about a full minute networking is restored and I
can log in.
