I have question on password sync filters. here is my scenario

I have edirectory/idm installed on one of windows DC which belongs
domain A. Now i want to sync user/passwords from different domain which
is B to edirectory. In domain B,its got 4 DC's which are located in
different
subnet's.

so my question here is, is it best way to install the remote
loader/password sync filters on one of the domain B domain controller
(allowing remote access)
or
install remote loader/password sync filter on one of the domain B
domain controller and install the password sync on rest of the domain
controller.

I see many threads recommands installing password sync filters on all
dc's. in this case how the communication happens between those password
sync filters and the remote loader?

I see ports 135,137,138 and 139 should be open in the following doc

'Novell Documentation'
(http://www.novell.com/documentation/...a/bow0k9b.html)

But I'm clearly not sure why these ports need to be open.

It would be great if some one explain

Thanks for help
