I'm looking for input from other institutions out there that are using the samba PDC/BDC setup. At our institution we have the potential for nearly 500 network clients on our domain and we are considering expanding that to 1,000 clients. According to John Terpstra in his Samba-3 book there should be a BDC for every 50 network clients on the domain. We are currently running a solitary PDC with no BDC for our 500 client environment and things are relatively okay. Login times can be sluggish at times, but not too bad. What kind of setup do other folks have out there, and what do others beside Terpstra suggest in terms of this PDC/BDC relationship? K. -- Kelly S.
