[Samba] samba & ldap

[Rosilene Pagani]

Hi,
I'm new here and I have a doubt...
I'm work with windows 2003 server and now i would change to llnux. My doubt
regards the share of my server: to authenticate my users what is better:
samba tdb or ldap? For us is not necessary an active directory, domain,
ecc... I need only a file server and I have arounud 400 users...Anyone have
experience? Any suggestions?
Thanks in advance!
