samba - Sep 2007 - ERROR: failed to setup guest info [3.0.23c]

Hi,

Trying to setup Samba to use an LDAP backend. I'm also using it with NSS 
which is working fine for all the unix related stuff (i.e. i can finger 
accounts etc).

When i start samba i get the following error:

Sep  5 19:42:57 staging1 nmbd[30805]: [2007/09/05 19:42:57, 0]

Sep  5 19:42:57 staging1 smbd[31035]:   ERROR: failed to setup guest info.

Here is the config i'm using:

#/usr/local/etc/smb.conf
#======================= Global Settings 
====================================[global]
   log level = 5
   workgroup = foo
   server string = foo Server
   security = user
#   passdb backend = tdbsam
   passdb backend = ldapsam:ldap://localhost
   ldap suffix = ou=windows,dc=foointernet,dc=com
   ldap user suffix = ou=users
   ldap group suffix = ou=groups
   # change password with  'smbpasswd -w <password>'
   ldap admin dn = cn=Manager,dc=foointernet,dc=com
   load printers = yes
   log file = /var/log/samba/log.%m
   max log size = 5000
   dns proxy = no
   store dos attributes = yes
   nt acl support = yes
   inherit acls = yes
   map acl inherit = yes
   obey pam restrictions = Yes
   ldapsam:trusted = Yes

[tmp]
   comment = Temporary file space
   path = /tmp
   read only = no
   public = yes

Had almost exactly the same setup working with 3.0.10-1.4E.1 with no 
problems.

Any and all help appreciated!
