How to enable contact object for communications server? RRS feed

  • Question

  • Hi all,


    After install OCS Server, I am able to enable AD user for communication server, but it doesn't work for contact objects. There is a communication property in contact objects, and I can do some sip configuration in there but when I click "OK" button, I received The following error message

    "Cannot save the settings because this contact does not have valid originator SID field in the Active Directory(AD)."

  • I think it doesn't work for contacts, because in that case there are no user in Active Directory for authentication and you need a user and a certificate (in case of TLS communication) to be able to connect the client through your front end.


    If you are trying to enable a external user to use a client and connect to your OCS I think that the best way to do it is to create a PIC and integrate your OCS with MSN (for example) and then add the external contact to your contact list. Just reminding that in this case you would need a Edge Server in your DMZ Network, a valid "External" Certificate and a Reverse Proxy for that.

  • That is correct, OCS does not allow for anonymous user access (outside of joining a Web Conference) and Active Directory Contact objects do not have any credentials associated with them and cannot be used to authenticate a session.


    What functionailty are you trying to accomplish?  Contacts typically represent external users which, and even if you created a mail-enabled User Account, would have no way to use the system unless you deployed the OC client to them and allowed external access to those users.
