Wild Card SSL cert with alias domain RRS feed

  • Question

  • User309480997 posted

    Not sure how to ask this or describe this but here goes.

    there are dns entries pointing https://obapp.abc.com to the correct IP address

    SSL wild card cert that is set for *.abc.com 

    IIS server lives on domain xyz.local

    IIS server name is abc123

    when I try to access the site using https://obapp.abc.com/startpage

    I get a login prompt from IE

    I have the site in local intranet zone

    I have the custom setting set to auto logon

    Is this possible? I'm used to seeing wild card certs like *.xyz.local not set to an alias

    Thanks in advance

    Hi rmellnick,

    Could you access the site under basic authentication? Secondly, could you see the auth information in fiddler. Is obapp.abc.com a public domain? I'm not familiar with IIS dns. How did you add the abc.com to your xyz.com DNS zone? Use a different domain for authentication may cause some Kerberos authentication issue.

    Best Regards,

    Yuk Ding

    Review every words of this KB article,


    and also use a tool such as Fiddler to investigate further into the requests/responses. IE can prompt not only for failed authentication, but possibly others, so only tools like Fiddler can tell more about the prompt.
