password protected shares

i'm using a samba 2.0 server running slackware linux and a win98 client.
when im creating password protected shares on the linux machine and adding the user and a password to the smbpasswd file i still can't use the shares. here's how the share look in my smb.conf file:

[anders]
comment = anders' home
path = /home/anders
writeable = yes
valid users = anders
public = yes


well, when i try to use the share i have to type in a password. i'm sure i'm typing the right one, but it's not accepted anyway. "anders" is the current win98 user (do i have to log in in a special way so samba knows who i am?)
