We have a server running SCO unix 5.04. This is used to authenticate our Win95 clients when they log on (as domain controller), provide shares and so forth. Now we have another server running linux 2.0.30. Both use SAMBA 1.9.19p10. and encrypted passwords. We would like to control access to shared folders on the LINUX machine authenticated using username/password pairs, prefereably using the SCO box for security. This looks simple, using security = server password server = # IP number of SCO box ..but the request is denied. In other words, it just doesnt seem to work. What have I missed? This is part of the SCO boxes smb.conf file - domain master = yes preserve case = yes short preserve case = yes unix password sync = yes case sensitive = no logon path = \\Bedford\profiles\%U server string = Bedford Samba Server os level = 16 domain logons = yes logon script = scripts\%m\%U\logon.bat printcap = /etc/printcap printing = sysv security = user encrypt passwords = yes browseable = yes guest account = guest max log size = 256 share modes = yes strict locking = no locking = yes socket options = TCP_NODELAY passwd program = /opt/K/SCO/Unix/5.0.4Eb/bin/passwd %n workgroup = WORKGROUP passwd chat = "*default is 1):*" \n "*New password:*" %n\n \ "*Re-enter password:*" %n\n directory mask = 0777 map archive = no writable = yes browseable = yes ..and this is from the Linux boxes smb.conf file -- [global] os level = 0 browseable = yes read only = no printing = sysv share modes = yes server string = Intranet Server getwd cache = yes workgroup = WORKGROUP create mode = 0777 map archive = no printcap = /etc/printcap max log size = 256 browseable = yes encrypt passwords = yes socket options = TCP_NODELAY writable = yes guest ok =yes load printers = yes # password server = 132.147.160.1 #IP Number of SCO Box. # security = server errr - help?
