System: NetBSD miyu 1.5_ALPHA2 NetBSD 1.5_ALPHA2 (MIYU) #12: Thu Sep 21 13:13:38 MEST 2000 feyrer@miyu:/ccd0/cvs/src-1.5/sys/arch/i386/compile/MIYU i386


>Description:
	usermod(8) sets some fields in /etc/(master.)passwd to values
	it should not.

>How-To-Repeat:
	1.
	miyu# grep ^feyrer /etc/passwd
	feyrer:*:102:100:Hubert Feyrer,,,:/home/feyrer:/usr/pkg/bin/tcsh
	miyu# usermod -g wheel feyrer
	miyu# grep ^feyrer /etc/passwd
	feyrer:*:102:0:/usr/pkg/bin/tcsh:/home/feyrer:/bin/csh

	2. 
	miyu# grep ^feyrer /etc/passwd
	feyrer:*:102:100:Hubert Feyrer:/home/feyrer:/usr/pkg/bin/tcsh
	miyu# grep ^ingres /etc/group 
	ingres:*:74:ingres
	miyu# usermod -G ingres feyrer
	miyu# grep ^ingres /etc/group
	ingres:*:74:ingres
	miyu# grep ^feyrer /etc/passwd
	feyrer:*:102:100:/usr/pkg/bin/tcsh:/home/feyrer:/bin/csh

	Note that Real name and Login shell are wrong now. (That's also
	why my realname is not on this and my last PR, 11071).
