[sugj-tech:7118] TOSHARG-BDCの訳でわからないところ

[ribbongw master]

The netlogon share has to be replicated from the PDC to the
BDC. This can be done manually whenever login scripts are changed,
or it can be done automatically using a cron job that will replicate
the directory structure in this share using a tool like rsync.

はわかるとして、

 The
use of rsync for replication of the netlogon data is not critical to
network security and is one that can be manually managed given that
the administrator will make all changes to the netlogon share as
part of a conscious move.

の意味がどうしてもうまく取れません。

どなたか是非ヒントいただけないでしょうか。
