Samba – Cannot Connect To Home Directory From Windows Via Samba

I changed the password of linux user "user123" on my Suse box and noticed that the previously working Samba login that I used to access its home directory from Windows did not change along with it. So I did this to ensure the 2 passwords were the same:

smbpasswd -x user123; smbpasswd -a user123; smbpasswd -e user123
Failed to find entry for user user123.
New SMB password:
Retype new SMB password:
Added user user123.
Enabled user user123.

Afterwards, I noticed that I could no longer access that directory (/home/user123). Windows response when I press for further details was that I "don't have permissions to access \ip.of.samba.share\user123" Here is my smb.conf file:

# smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

And, by the way, I have restarted Samba:

/etc/init.d/smb restart
Shutting down Samba SMB daemon  done
Starting Samba SMB daemon   done

Any ideas?
