VPN Site to Site and port 389

I would like to know when using Cisco Site to Site VPN, so that branches of a company will work as they are all in the same LAN, whether we need to poke hole for LDAP in ASA firewall, or the Authentication method used in Site to Site VPN  Wizard will be enough to make Active Directory authentication work seamlessly without opening port 389 in ASA firewall ?


Any Clarification on this will be very much appreciated.

Thank you.

Can't attest to the Cisco configuration, but normally a VPN allows ALL Traffic and ALL ports to flow to and from.

A Site to site VPN usually (unless you've specified otherwise) has all ports open. However if possible your client should have a domain controller on their local site.  If that's not possible make sure their primary DNS server is a DC and not a public DNS server.
