[Samba] Multiple ldap backend on the same PDC - samba 3 rc3 ?

[jean-marc pouchoulon]

How can I have multiple backend on one samba pdc.
Samba seems to accept this two lines in the smb.conf.

passdb backend = ldapsam:ldap://ip-one/,guest
passdb backend = ldapsam:ldap://ip-two/,guest

With the cache mechanism on xp client , I am not able to see if it works
et whitch ldap server answer.
What is the best way to have Multiple ldap backend on the same PDC ?
Is it possible.

Good week-end.
