We're not using LDAP, we're using security=server to a Windows 2000 server providing NTLM services... but what you describe sounds close, very close. We keep the virtual host capped at 64 meg ram and 128 meg swap, as it improves performance... I think this keeps us from having "thousands" of processes, but we definitely get upwards of 50+ extra ones. So what's the cure for this, folks? Local smb.passwd authentication? Our SuSE SLES 7 hosts running Samba samba-2.2.0a-56 don't have this problem. Only the newer SLES 8 (service pack 3).
