It is much easier to do decryption with wireshark when the keytab is available for every host in the domain. Running 'net export keytab <keytab name>' will export the current (as pointed to by the supplied smb.conf) local Samba4 doamin. (This uses Heimdal's 'hdb' keytab and then the existing hdb-samba4, and so has a good chance of keeping working in the long term). Andrew Bartlett
