Symptoms

I updated K2 to the latest version and now receive "Could not find the Issuer to use for authentication" when accessing the K2 App from a sharepoint list. I followed the instructions here: http://help.k2.com/onlinehelp/k2blackpearl/icg/4.6.7/webframe.html_claims_authentication_configuration.html but this did not resolve the issue.
 

Diagnoses

-Designer site can not be opened. Receive error "No Realm Entries for: https://k2.denallix.com/Designer/ was found.
-This environment does not use SSL so all links should use http. Many if not all of the tables contained an https link. Changed URLs in claims tables for realms and issuers to use http but this had no effect on viewing designer site or clicking on the K2 App from a sharepoint list.
-Ran through configuration wizard to make sure bindings were set to default non-SSL URL
-Set defaults for Designer URLs in Environment library to use http and not an https URL
-Some setting is still forcing designer to look for an https link when we want the http url.
 

Resolution

Upon checking the web.config file for designer at C:Program Files(x86)K2 BlackpearlK2 smartforms DesignerWeb.config. We noticed that the realm for the node wsFederation... was set to an https link. See below:


The realm url was changed from "https://k2.denallix.com/Designer/" to "http://k2.denallix.com/Designer/", removed https and changed to http. Did an IIS reset to enable the new configuration to be picked up. Ensured that all values in Claims Tables were set to use http and not https. After that designer loaded with no issues.
