Hi all i have a samba pdc (samba 3.0.21c) with openldap (openldap 2.3.19) on Redhat Enterprise Linux 4 ES (kernel version 2.6.9-5smp). and 2 domain member server(Linux same architecture as server). All my windows clients are windows 2000 professional joined to my pdc. Right now i have configured pdc without winbind. and started using it. while configuring the pdc. i could not configure winbind, and winbind was not working so stopped winbind, and started configuring PDC, if i start winbind and configure it , will it effect my existing pdc, or do i have start from the first. is pdc without winbind a best option or with winbind please guide me. Regards Niranjan
