[Samba] Samba and LDAP authentication backend

[srtt.be - Michel Lombart]

Thank for your fast reply Karel and thak at Rowland as well.

I do not have any PDC in that network and any domain neither. All 
follows the workgroup model.

And yes, net getdomainsid in both servers are the same ... nothing !

SID for local machine oldone is: S-1-5-21-3641741432-4083152458-129815128
Could not fetch domain SID


SID for local machine newone is: S-1-5-21-2324203820-3887545065-2044117837
Could not fetch domain SID

Both SID are also in the LDAP under an object sambaDomainName and I 
noticed that a SambaDomainName=WORKGROUP as the same SID as the old 
server. They came when the server tried to connect the first time at the 
LDAP.

Both config files are identical, server names shares definition 
excepted. Here are the global section :

[global]
         log file = /var/log/samba/log.%m
         passwd chat = *Enter\snew\s*\spassword:* %n\n 
*Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
         obey pam restrictions = yes
         posix locking = no
         dns proxy = no
         force group = nogroup
         encrypt passwords = true
         passdb backend = ldapsam:ldap://172.20.0.150
         passwd program = /usr/bin/passwd %u
         ldap ssl = off
         ldap user suffix = ou=users
         ldap machine suffix = ou=machines
         ldap group suffix = ou=groups
         netbios name = serverName
         server string = serverName
         ldap passwd sync = yes
         ldap suffix = dc=domain,dc=be
         workgroup = WORKGROUP
         os level = 20
         force user = nobody
         ldap admin dn = "cn=admin,dc=domain,dc=be"
         security = user
         syslog = 0
         panic action = /usr/share/samba/panic-action %d
         max log size = 1000
         pam password change = yes

Thank for your help.
