few questions on winbindd-ntlm_auth interface

[kiran kumar]

Few questions on winbindd architecture in Samba-ver: 3.4.4/source3.
Our setup has a Squid-Proxy configured to do 'NTLM Authentication'
using ntlm_auth and winbindd from Samba-3.4.4. Functionally this works
but I'm concerned about its scalability. To be precise, how many
instances of "ntlm_auth" should I launch in a setup of 1000 Users all
belonging to single domain?
