Hi all I have a samba PDC(3.0.21c with openldap 2.3.19) . and some file servers as domain member server( linux with samba 3.0.21c). i would like to setup BDC. according to samba documentation BDC's to have slave ldap server is optimal solution. i have 3 different locations, so at 1 location i would like to setup PDC, and another 2 location's i would like to setup BDC's Q) can i have this type of setup ? Q) if i can, how do i configure DNS of the BDC, whether it should be secondary dns server or it should also have a master DNS server of the same domain. By default PDC's have the DNS with DHCP (ddns implemented). Regards Niranjan
