I don't think I can be of much further help, since smbnetfs and fuse are unfamiliar to me (except at concept level).
Anyway, here's a few more shots in the dark: - Make sure DNS reverse records are correct - Whatever runs the fs share needs to have access to the local /etc/krb5.keytab Debugging Kerberos can be a real PITA, as the MIT libs don't show too relevant info about failures, but instead mask failures behind more generic errors. I've tried stabbing the source a bit to circumvent this, but it's not such an easy task and would only be useful for debugging anyway, since revealing too much information about a failed authentication can easily lead to security issues. -Atte On 6/12/08, Derek Taylor <[EMAIL PROTECTED]> wrote: > On Sun, 08 Jun 2008, Atte Peltomki wrote: >>smbclient (and other samba utilities) do not refer to krb5.conf when >>figuring out the kerberos realm. >> >>you will have to put to your krb5.conf on both client and server: >> >>[domain_realms] >> cifs.example.com = realm.example.com > > I've done this step, but there seems to be no difference.
