Apple IOS application is not working correctly after adding a SSL certificate to the RES ONE Identity Director environment

Version 6

    Problem

     

    After adding or changing an SSL certificate, the RES ONE Identity Director Apple IOS application is not working anymore. Users are unable to logon anymore with their iPhones or iPad’s, the logon screen appears but when the user clicks logon, nothing happens.

     

     

    Solution

     

    This issue is resolved in Ivanti Identity Director 2018.1.

     

     

    The following workaround can be used to (temporarily) solve this issue.

     

    Workaround:

     

    Temporarily disable HTTP2 in IIS10

    To disable HTTP/2 on Windows 10 HTTP.SYS, set the following registry value on the Microsoft Windows 10 desktop or in the Microsoft Windows 2016 server:

    System Key:  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters

    Value Name: EnableHttp2Tls

    Data Type: REG_DWORD

    Value Data: 0

     

    System Key:  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters

    Value Name: EnableHttp2Cleartext

    Data Type: REG_DWORD

    Value Data: 0

    EnableHTTP2TLS is only necessary when the failure is within HTTPS

    EnableHttp2Cleartext is only necessary if the failure is within HTTP

     

    An IISreset is necessary for the changes to take effect.
