I reported this issue to this list about a month ago (5/10-5/13). There were changes to the security defaults in Samba 3.6 (see below). I was unable to get BackupPC (or more specifically, smbclient) to work using the option on either the command line or in smb.conf.
I have added this information to the tolaris, redhat, and debian postings. Brad Changed security defaults ------------------------- Samba 3.6 has adopted a number of improved security defaults that will impact on existing users of Samba. client ntlmv2 auth = yes client use spnego principal = no send spnego principal = no The impact of 'client ntlmv2 auth = yes' is that by default we will not use NTLM authentication as a client. This applies to the Samba client tools such as smbclient and winbind, but does not change the separately released in-kernel CIFS client. To re-enable the poorer NTLM encryption set '--option=clientusentlmv2auth=no' on your smbclient command line, or set 'client ntlmv2 auth = no' in your smb.conf -----Original Message----- From: Tyler J.

Each describes my issue well.
