[Samba] Multiple samba servers with LDAP

[cooper mail]

I was wondering what the best practice is for setting up several SAMBA
servers in a SAMBA domain all on the same LAN.  Here is what I am
looking at

PDC: LDAP, Samba, nss_ldap, pam_ldap
Member1: Samba, nss_ldap, pam_ldap
Member2: Samba, nss_ldap, pam_ldap
Member . . . .

Should I set the member servers up with:
Security = domain
and join the severs with net rpc join

or, whould it be better to set them up with:
passdb backend = ldapsam:ldap://pdc.domain.com
security = server

Do you see where I am going?  If you need more details to answer, let me know.

Thanks,

cooper
