I'm in the process of setting up a samba file server, and I'd like to set it up so users can authenticate with their Kerberos realm credentials. It seems that every article I read wants me to bind the thing to a domain, and authenticate that way. The only problem with that is user accounts aren't domain accounts, they are "shadow" Kerberos realm accounts (forgive me, I'm not a windows admin) when I bind samba to our AD, those shadow accounts don't work, but real domain accounts do. Users don't have real domain accounts. I've obtained a service keytab, and modified the smb.conf following multiple articles online, and get 'could not look up dcs for domain "REALM"' and (the value in my realm field). The realm isn't a real host. it's an MIT realm. My system is kerborized, and the values in krb5.conf work for system-auth. Thanks in advance, Dann
