I have Samba 2.0.4b running on HP-UX 10.20. If I have an automatic drive mapping occur in NT or Win95 to one of my Samba shares, then the user is authenticated as the guest user. If I don't have an automatic drive mapped, then the user is authenticated as their actual username when navigating to the share in Explorer. The users all have Unix accounts and the authentication is occurring on an NT domain controller. The NT domain controller is identified as the WINS server and WINS support = no. If I remove the guest account on the HP-UX server, then with the automatic drive mapping the user does get authenticated as themself and the following message shows up in the log file: "Username guest is invalid on this system" I created the guest user because in one of the Samba doc files it said you'd have problems if you didn't have a guest user, but I don't understand why this is occurring. Any ideas would help. Thanks, John Holmes Skagit County Information Services Phone: 360-336-9370 Fax: 360-336-9308 email: johnsh@co.skagit.wa.us
