Thanks for your quick response.

Yes samba relies totally on LDAP, no groups or user reside on in local 
files, however i put the "ldapsam:trusted = yes" line in the smb.conf 
put it kill smbd process silently as soon as i have started it :(

I have tried this on 3.0.13, havent yet on 3.0.11 as thats the 
production version!

logs show only this:

Starting Samba daemons: nmbd smbd[2005/04/13 14:06:44, 0] 
   smbd version 3.0.13 started.

my smb.conf looks like:

netbios name = quigon1
workgroup = uni-staff
enable privileges = yes
passdb backend = ldapsam:"ldap://vila.sunderland.ac.uk 
ldapsam:trusted = yes
ldap delete dn = no
ldap suffix = dc=sunderland,dc=ac,dc=uk
ldap machine suffix = ou=uos,ou=domains,ou=network
ldap group suffix = ou=groups,ou=filestore
ldap admin dn = "cn=Directory Manager"
ldap ssl = on
ldap passwd sync = yes
idmap backend = ldap:ldap://vila.sunderland.ac.uk
ldap idmap suffix = ou=groups,ou=filestore,dc=sunderland,dc=ac,dc=uk
os level = 33
log level = 2
preferred master = no
domain master = no
local master = no
security = user
domain logons = yes
logon home =
logon path =
username map = /mnt/netlogon/usermap

         comment = netlogon share
         path = /mnt/netlogon
         read only = yes

Thank you,
