Comodo UC Cert and Public IM RRS feed

  • Question

  • Does anyone know if the comodo UC cert (down the chain from entrust) supports Public IM?


    I've read that certs using intermediate certificates will not work for this purpose but I can't seem to get my hands on one that comes straight from a root CA.


    Also is the error from communicator when trying to talk to public IM contacts using the comodo cert on the edge access one that could be caused by a certificate error or another gremlin in the works? I am aware that I could be asking a obscenely obvious question but google has failed me on this one.

  • Hi David,


    I would suggest to use the certificate from Verisign, Thawte, GTE, ValiCert, SecureNet, SecureSign, and
    Equifax.... There are some others as well which can be used for the PIC purpose, but comodo deosn;t seem to be valid.
