Tue Jan 22 11:36:57 UTC 2019

The autobuild test system (on sn-devel-144) has detected an intermittent failing test in 
the current master tree.

The autobuild log of the failure is available here:

The failure seems to be in the "samba-py2" suite, whose build logs are available here:

    netcmd: Try to improve domain backup error message

    I ran this command as non-root by mistake and didn't find the error
    message particularly helpful. Tweak the error message so it reminds the
    user that they should be root. Also display the path we're looking for
    the sam.ldb file in, to give them more clues.
