Subject: traffic_replay: Rework machine accounts to remove redundant code
X-Git-Tag: tdb-1.3.17~847
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a0b5f4b7b05b8ea2bf061b8af5b702aa14a7a5a5;p=thirdparty%2Fsamba.git

traffic_replay: Rework machine accounts to remove redundant code

generate_users_and_groups() now generates the machine acounts as well as
the user accounts, so it seems there's no need to also have
generate_traffic_accounts(), which does the same job.

Instead, we can just pass through the number of machine acounts to
generate_users_and_groups() and delete the other function.

Also updated generate_users_and_groups() so that machine_accounts is
no longer optional (we want to create machine accounts in all cases).
