Forefront GAL sync across forests RRS feed

  • Question

  • Hi,

     I've been looking into setting up Exchange GAL sync between 2 separate organizations (Exchange Forests). The requirements are for a 1 way sync (read GAL and update/delete/add contacts to GAL in org B as needed). I know FIM 2010 can do this, but I'm not sure about the requirements\setup.

    Reading the 'before you begin section' at mentions Sharepoint Services & website. 

    Organization A in my scenario is large organization (around 6000 users) and organization B is small, I'd rather avoid installing Sharepoint 2010 if I can help it. Would I need to install and configure Sharepoint 2010 in both organizations for FIM 2010?

    For simplicity I'm looking at alternatives:

  • Hi,

    You only require the FIM Synchronization Service in order to achieve this.

    Therefore you do not need the FIM Service (Portal); therefore you do not need any Sharepoint components either.

  • Thanks,

    To install FIM sync between 2 organizations, I'm assuming I'd need the client and server component?

    Am I right in thinking I'd need the server in organization A (holds master GAL) and the client in organization B (holds the GAL to be modified)?

    Also, I take it terms of communications between the two organizations, the main things I would need are ports 5725 and 5726 for the client to server communication and the server portal being contactable via https?

  • Hi,

    Install one FIM Sync server in Org A.

    Setup 2 GALSYNC MAs, one MA to Org A and the other MA to Org B.

    The port you would need open is either LDAP or LDAP over SSL (depending on your security requirements).

    Please take a look at the following resource for all the information & walkthroughs:

    Hope this helps,
