Connections do not clear

I could suggest patience. But to assist that you may have a look at the "watchdog" setting (time before the first, interval between). They take care of no longer responding connections, and that system will remove those sleeping connections.
Whatyou're looking for is "set delay before first watchdog packet", "set numbre of watchdog packets" and "set delay between watchdog packets". See http://www.novell.com/documentation/lg/nw4/utlrfenu/data/hgdzhwr7.html for more details.

You didn't say, but to make sure they are cleared every night, set time restrictions to deny access between, say, 0200 - 0300.
You can get them to manually clear the connection by right-clicking the red N in the system tray, or Network Neighborhood, and selecting "Netware Connections...". Then, click on the tree or server you want to clear from, and select "Detach".
I know this isn't exactly what you want, but this has always been a "quirk" of Netware clients past 4.1.
If you search Novell'sKnowledgebase - as I have - you'll see it basically says "So what? Live with it."

Here is another way to clear connections, but it is more for instances in which you cannot see the user is connected at all, but still get the "... too many simultaneous...".
At the System Console prompt of a server holding at Least a R/W replica, type "LOAD DSREPAIR -n1". This clears the connection table of stuck connections.
