    Hello,

    We are trying to import and assign third party certificates from Comodo (free for 90 days) for OCS 2007 R2 Edge role external interfaces without success. We have used OCS 2007 R2 deployement and configuration wizard (from OCS installation folder) to achieve this goal: requested all necessary certificates for external interfaces and issued from Comodo CA. The main thing here that we have recieved these certificates in .crt format. OCS 2007 R2 deployment and configuration wizard let us import .cer or .p7b type certificates.
    So we have imported using mmc snap-in to personal certificate store and have tried to export to .p7b format. After that we used deployment and configuration wizard to import and assign but with no luck (no certificate for external interface is appearing in the window). The problem is how to import .crt certificates using deployment wizard?

    P.S. For OCS 2007 R2 internal interface we have used private Certification Authority. We have requested/issued and saved certificate in .p7b format. After that we could import and assign this certificate without any issues.

    Thank you for hearing.

    Hello,

    Just want to inform that we have solved this issue. We have called to Comodo support and requested a certificate in .cer format. After that we used deployment and configuration wizard to import and assign certificates.

    Try importing the certificates into the Computer Store directly using the Certificates snap-in and then go into the Edge properties Interfaces tab and assign the certificates to each role manually.  The wizard is not necessary and sometimes can be problematic with certain certificate file formats.

    Although this article pertains to Root certs, the process is the same, just import the certs into the Personal folder.

    When we are manually importing certificates in Computer Store (Personal location) the certificates missing private keys...

    By the way we are configuring on Windows Server 2008 R2. Maybe that is a problem?

    Thank you for hearing.
