This is extremely timely for me, since I was looking into this subject
just this morning.
I have about 11,500 users on an smbpasswd file! :-o This does not work
very well, and we recently reached a breaking point. I looked into
tdbsam, figuring that that might be the easy way to go (I do not need
replication, as this backend is running a computer lab, not 11,500
concurrent users). The fact that my setup is two orders of magnitude
larger than the recommendation for tdbsam gives me pause.
Can anyone comment on this? I'm sorta in an emergency situation, not a
design situation... I'm almost looking at MySQL because that is
something that I could reasonably deploy in the next 48 hours. LDAP
would require at least some substantial reading for me, I'd think. Maybe
