Problem - smbpasswd does not seem to be recognizing my "add user script" option to automatically create Unix users when adding a samba user. I am running Samba version 2.2.8a (from source) on a Linux (Redhat 8.0) system. Relevant lines from smb.conf: [global] server string=Samba Server netbios name = smbpdc security = user domain logons=yes domain master = yes

Hi Everyone, the new 3.0.4 Samba installation seems to work find except that from time to time but at least a couple of times a day one or more smbd processes start running at 20%-40% CPU each and 6 nscd processes then share the remaining CPU power. System 70%-80% users the rest 20%-30%. Load rises fast to over 4. I'm sure that each such process is just idling, but why does it engage so much
