autobuild[sn-devel-144]: intermittent test failure detected

Mon Nov 5 05:37:24 UTC 2018

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:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-05-0637/flakey.log

The failure seems to be in the "samba-nt4" suite, whose build logs are available here:

   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-05-0637/samba-nt4.stderr
   https://git.samba.org/autobuild.flakey.sn-devel-144/2018-11-05-0637/samba-nt4.stdout

The top commit at the time of the failure was:

    traffic: Machine accounts were generated as critical objects

    Due to the userAccountControl flags we were specifying, the machine
    accounts were all created as critical objects. When trying to populate
    1000s of machine accounts in a DB, this makes replication unnecessarily
    slow (because it has to replicate them all twice).

    This patch changes it so when we're just creating machine accounts for
    the purpose of populating a semi-realistic DB, we jsut use the default
    WORKSTATION_TRUST_ACCOUNT flag.

    Note that for the accounts used for traffic-replay, we apparently need
    the existing flags in order for the DC to accept certain requests.
