1 comment to Communicator Automatic Sign-In when SIP Domain Different from AD Domain

  • ECL

    Hi, Great post :) I have question which I hope you can help with.

    Does automatic sign-in work when the OCS installation is in the resource forest?

    I find the users able to login in the Accounts forest when they manually enter

    their SIP:email. But I just can’t get it to auto populate the sign on the 1st

    login. P.S automatic login works fine in the resource forest. I think it is

    something to do with the fact that the Accounts forest does not have the users

    SIP details hence the OCS client can’t query AD for the users SIP address on


    Any pointers will be most welcomed.
