[Samba] Help with samba/winbindd issues

[Jennifer Fountain]

i am having an issue with samba and winbindd

copy of my smb.conf

# Samba config file created using SWAT
# from ws09573.rb.net (10.27.52.177)
# Date: 2002/10/17 16:41:29

# Global parameters
[global]
	workgroup = domain1
	netbios name = server1
	server string = SERVER1_SAMBA
	interfaces = lan4 127.0.0.1
	bind interfaces only = Yes
	security = DOMAIN
	encrypt passwords = Yes
	password server = DC1
	wins server = 1.1.1.1
	winbind uid = 40000-49999
	winbind gid = 50000-59999
	template shell = /usr/bin/ksh
	winbind use default domain = Yes

[Finance]
	path = /tmp/finance
	valid users = finance

[jf]
	path = /tmp/jfountain
	username = jfountain
	valid users=jfountain
	read only = No

i can access my JF directory if I do not have valid users. if i do have
valid users,  i get the following:

# tail log.smbd
