[Samba] ldap and sharing SID

[James]

without creating a domain for samba is there a way i can get to or three 
samba servers to share the same SID for authentication for different shares?

say have:
server1
server2
server3

edit their ldap entries for their SID and set them the same
and use
security = user

have them all user the same ldap passdb for authentication?
or is there more to it than that?
server1 is already working fine with ldapsam
cause i'm trying to login on server2 that has the same SID as server1 
that's already working on ldap but i get a
smbd/service.c:make_connection_snum(920)
  '/home/tester' does not exist or permission denied when connecting to 
[tester] Error was Permission denied
