Google Apps Directory Sync LDAP port 389

I'm configuring Google Apps Directory Sync and forward port 389 to my Active Directory server.

It works. But is this a security risk?

If yes, what are the steps/requirements for using LDAP+SSL for the connection?

I run the directory sync on the domain controller as well and I have forwarded port 389 to the dc.
Is that a risk?
how do you mean you have forwarded port 389 on the dc.

all you need to do is set it as attached image, changing your base DN and authorised user

I can't see any security risk as it is done locally (so no network sniffing), and port 389 is open anyhow

I did the forward in the firewall
Don't do that, there is no need. That is a security risk

The directory sync reads the LDAP details locally and then uploads the information to Google/Postini through HTTP/S
