After installing 9.1 I see the following error on the login screen:

Error Message

Steps I followed:

  1. Updated XP0-SingleDeveloper with ".dev.sc.local" to the site names
  2. Ran the installation using XP0-SingleDeveloper.ps1 and SIF 2.0
  3. Updated IIS host binding to use https for "sc910.dev.sc.local".

After speaking with my friend @kamsar, he pointed out the CORS origin on the Identity Server Instance needs an update.

The Identity Server doesn't allow logging in from just any url, for security reasons.

  • Open the file C:\inetpub\wwwroot\sc910.identityserver.dev.sc.local\Config\production\Sitecore.IdentityServer.Host.xml
  • Add a new AllowedCorsOriginsGroupN
  • Recycle the Identity Server Application Pool

Below you can see the new setting added as Group2:



Found this link to the 9.1 documentation.


In addition to Michaels correct answer: It is also possible to define the AllowedCorsOrigins pipe-separated. I also stuck on this and found the description in the IdentityServer WDP zip (parameters.xml):

    <parameter name="AllowedCorsOrigins" description="Pipe-separated list of instances (URIs) that are allowed to login via Sitecore Identity.">
      <parameterEntry kind="TextFile" scope="website\\config\\production\\Sitecore.IdentityServer.Host\.xml" match="PlaceholderForClientOriginsGroup" />

You can define the Origins like that:

    I see value in using the pipe delimiter in order to make these entries match those from sxa tenants. – Michael West Dec 17 '18 at 13:06

    Do you have an example of how to apply this as a patch? Something that can be dropped into a folder? – Michael West Dec 17 '18 at 13:15
  • unfortunately not :( it is set by the XP0-Single-Developer.ps1 --> $AllowedCorsOrigins = "http://$SitecoreSiteName"... maybe you can adjust the script to have more $SitecoreSiteNames – monkey.dsc Dec 18 '18 at 12:12
