Nomachine user limit

Some days ago I found a strange user limitation for Nomachine Server – I know that it was the “free” edition. The user limitation came end of 2009 and my server without limitation running since 2008
I think I should visit sites of OpenSource/Free projects ofter

/usr/NX/bin/nxserver --userlist
/usr/NX/bin/nxserver --userdel username

Very very dirty hack to prevent the limitation – Create a cron which runs every minute and remove all users:)
