The autobuild test system (on sn-devel-184) 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-nt4" suite, whose build logs are available here:
The top commit at the time of the failure was:

    s3:auth: explicitly add BUILTIN\Guests to the guest token
    This changes ensures that smbd always adds BUILTIN\Guests to the guest token
    which is required for guest authentication.
    Currently the guest token depends on the on-disk configured group mappings. If
    there's an existing group mapping for BUILTIN\Guests, but LOCALSAM\Guest is not
    a member, the final guest token won't contain BUILTIN\Guests.
    For SMB2 the flag SMB2_SESSION_FLAG_IS_GUEST will not be set in the final SMB2
    SESSION_SETUP response, because smbd sets it based on the token containing the
    BUILTIN\Guests SID S-1-5-32-546.
    At the same time, the packet is not signed which causes Windows clients and
    smbclient to reject the unsigned SMB2 SESSION_SETUP response.
