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" suite, whose build logs are available here:

    netcmd: Add 'samba-tool group stats' command

    With large domains it's hard to get an idea of how many groups there
    are, and how many users are in each group, on average. However, this
    could have a big impact on whether a problem can be reproduced or not.

    This patch dumps out some summary information so that you can get a
    quick idea of how big the groups are.
