hello, i want to configure my sambaserver like this: sambaserver, only user "me" is allowed to use share "root". this user exist in the nt 4 domain "DOMAIN 4". if user request the share "root" it will be authenticated by the pdc (primary domain controller nt4). user don?t need to type his password, cause he is already logged in the domain. if password is still requested the password is the nt4domain password of the user not the password in the linuxmachine from user. i read the samba documentation and made some modifications in my smb.conf. a. password server =*, after that i used the server manager for domain in my pdc and added the linuxmachine "SAMB" as ntworkstation or ntserver into the domain"DOMAIN4" b. smbpassword -j DOMAIN4 (report = joined domain) c. dann smb.conf umge?ndert ( security = domain, valid user = me, encryptd password = true ) d. user "me" exists in NT4 Domain controller and Linuxmachine. Unfortunately it doesn?t work yet. did i forget something? here is my smb.conf # Global parameters [global] workgroup = DOMAIN4 netbios name = SAMB interfaces = 192.168.2.207/255.255.255.0 security = DOMAIN encrypt passwords = Yes password server = * deadtime = 3 keepalive = 30 max open files = 500 shared mem size = 5242880 os level = 2 local master = No guest ok = Yes hosts allow = 192.168.2.0/255.255.255.0 [root] comment = root-verzeichnis path = / valid users = me writeable = Yes create mask = 0777 only user = Yes thanks in advance josef
