OCS 2007 Certificate issues RRS feed

  • Question

  •  

    I am having a problem installing OCS 2007 Standard Edition with the certificate.

    My internal domain name is different to my external domain name.

    Internal: cont.ad

    External: contosore.com

    I am deploying this version in only one server. When I create the pool I do not have a choice to change the name of the pool.

    Now, if I create a certificate to be installed in IIS named servername.cont.ad (Internal domain) when I install Office Communicator on the client PC I received an error with the certificate and all the features for web conferencing, web commponent are OK. If I create a certificate named servername.contosore.com (External domain) then I do not have the error with the certificate but the web component and web confrenecing cannot be accessed.

     

    Please, I am new installing OCS. How can I configure OCS 2007 to work properly.

     

    Thanks

  • Using seperate internal and external namespaces is very common (typically recommended in fact) and just requires a little planning in order to get everything setup correctly.

     

    Are you using both domains as configured SIP domains, or only the internal domain name?  I would recommend going back through the deployment guides are verifying that you configured each step correctly in relation to certificate Subject Name and SANs, DNS SRV records, pool name, etc.

  • Also, take a look at this article for some detailed steps on configuring OCS with split DNS zones.

  • Hello Elvys,

     

    We need to have SAN (Subject Alt name on the certificate) to make this setup to work.

     

    On the certificate-- name of the certificate should be your pool name . Like Servername.internaldomain.com and SAN will have 2 names, servername.internaldomain.com and servername.externaldomain.com. once you have this on the

    certificate all the OCS services should start.

     

    Enable Subject Alternative Names for the CA:
    certutil -setreg policy\EditFlags +EDITF_ATTRIBUTESUBJECTALTNAME2
    net stop certsvc
    net start certsvc

  • Using the certificate wizard in OCS is recommended, which already handles populating the SAN field.  By default the configured SIP domain names are entered here.
