The smbclient (3.5.11) in Ubuntu 11.10 returns the exact same errors as the smbclient (3.6.3) in Ubuntu 12.04 with one exception, the errors were ignored or skipped by BackupPC with 11.10 and are fatal with 12.04.

I believe the following from http://www.samba.org/samba/history/samba-3.6.0.html may be relevant.

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
