The following error appears:
WIF10201: No valid key mapping found for securityToken: 'System.IdentityModel.Tokens.X509SecurityToken' and issuer: 'https://login.xxxx.yy/adfs/service/trust'.
This issue appears if you don't have a good ADFS certificate setup in K2 table [Identity].[ClaimIssuer], or this certificate is started by invalid characters.
To verify the ADFS thumbprint, please follow these steps:
Step 1 (Manual approach or PowerShell) is mandatory, Step 2 is preferred, Step 3 should only be done if Step 2 cannot be completed.
Step 1 Manual approach - Get the Thumbprint from the Certificate:
- Get the new SSL thumbprint by using MMC:
Start → Run: mmc.exe Menu: File → Add/Remove Snap-in…
Under Available snap-ins, select Certificates and click Add.
Select Computer Account for the certificates to manage. Click Next.
Select Local Computer and click Finish.
Press OK to return to the management console.
- The certificate usually resides under the following category:
-- Trusted Root Certification Authority -> Certificates
- Open the specific certificate by double-clicking or right-click and selecting Open
- Go to the Details tab
- Scroll down until you find the "Thumbprint" Field and select it
- Copy the thumbprint at the bottom and paste into Notepad
You'll notice it has spaces and consists of lower case letters.
- Remove the spaces and change all the letters to uppercase (VERY IMPORTANT - it won't work with lower case)
- Finally, copy the finished string as you're going to need it later.
Step1 (other possibility by PowerShell):
Execute PowerShell as administrator and execute the following command:
Get-AdfsCertificate -CertificateType Token-Signing
$a = Get-AdfsCertificate -CertificateType Token-Signing
Step 2 (up to 4.6.11)
- Update the Thumbprint in K2 using K2 Management:
Open K2 Designer, Display System Object (Filter at bottom), All items > System > Management > Security > Forms > Manage Issuers
- Select the issuer in question
- Click the Edit button
- Update the thumbprint to the final copy created in Step 1 above - it should be uppercase with no spaces
- There shouldn't be a need to restart the K2 service, but if you don't see any immediate changes, you can restart the K2 Service and do an IISRESET
- You are finished.
Issuer: Federation Service Identifier http://ADFS.domain.COM/adfs/services/trust
URI: This is composed of two parts
• Default root site ADFS binding
• SAML 2.0/WS-Federation endpoint
Step 2 (4.7 and up) - Update the Thumbprint in K2 using K2 Management:
- Open K2 Management
- Browse to the following location using the left-hand-side navigation panel: -- K2 Management > Authentication > Claims > Issuers - Select the issuer in question. Click the Edit button
- Update the thumbprint to the final copy created in Step 1 above
- It should be uppercase with no spaces
- There shouldn't be a need to restart the K2 service, but if you don't see any immediate changes, you can restart the K2 Service and do an IISRESET.
Step 3 - Verifying the Thumbprint in the K2 Database
- Open Microsoft SQL Server Management Studio and browse to your K2 Database
Option (By script):
Execute the following script on the K2 Database:
To find the good Id, you can execute the following query:
SELECT * FROM [Identity].[ClaimIssuer]
- Double-check it has been updated by right-clicking on the Table and choosing "Select Top 1000 Rows"
Should the results display incorrectly, it would indicate that the thumbprint is the cause of the error.
To resolve this issue, direct database modification will be required. Please log a K2 Support Ticket on the K2 Customer Portal for assistance in resolving the issue.
