[Samba] Samba LDAP SID and Local SID

[Pavan]

Hi All,
 
        I am running Samba - 3 using a ldap backend, recently I have 
needed to change the domain of the computers as I am migrating to other 
server, I have the ldap database and populated the ldap database on the 
new server, but I am facing a problem with SID's as the SambaSID in the 
ldap backend is from the old samba server which is different from the 
current SambaSID(net getlocalsid) but Its not really feasible for me to 
create all the user accounts again on LDAP. Can any one advise me on how 
to get around this? Without changing the SID's I am unable to join the 
machines to the new domain and get an error *"o mapping between account 
names and security Id's" .
*
thanks in advance,
Pavan.
