The problem is that that the 'valid_login' function in 
user.sbin/user/user.c does not allow the $ character in login names - 
here is a patch for the -current user.c which fixes this (I originally 
did this for OpenBSD so haven't tested under NetBSD). If you don't feel 
like recompiling you can just create the account without the $ and then 
edit using vipw.
