>Description:
	
Updating the kernel and userland from 11/23/98 -current to 01/18/99 -current
has stopped allowing any users with usernames longer than 8 characters from
logging in.  Doing nothing but shortening the name via vipw allows the login
to proceed.  This appears to be related to getpwent() rather than a general
login failure, as it affects all programs attempting to deal with the
account (Samba, su, etc.).  The relevant change from 11/23/98 to 01/18/99
seems to have to do with the nsswitch code.  The default nsswitch.conf file
is being used, which specifies 'files' for passwd.  
>How-To-Repeat:
	
Create user with >8 character login name. vipw will accept the user just fine.
Any attempt to change to that user via login, su, etc. will fail.
