This issue occurs if the Keystore and Truststore are not initialized.

Follow the below steps to configure the Keystore and Truststore

Login to user admin through touch UI URL - http://localhost:4502/libs/granite/security/content/useradmin.html

Search for authentication-service and open it


Click on "Create KeyStore"
Enter the password and click OK



Click on "Create TrustStore"
Enter the password and click OK

Issue2:

14.05.2018 11:33:09.169 *INFO* [qtp1134377453-180] org.apache.sling.security.impl.ReferrerFilter Rejected empty referrer header for POST request to /saml_login

This issue will occur if the empty referrer is not allowed for the IDP host.

Follow the below steps to fix the issue

Login to config Manager - http://localhost:4502/system/console/configMgr

Locate "Apache Sling Referrer Filter"

Select "Allow Empty" and enter DP host in "Allow Hosts"

Issue3:

14.05.2018 11:47:58.087 *ERROR* [qtp1134377453-189] com.adobe.granite.auth.saml.binding.PostBinding Unable to receive SAML message. Could not read IdP certificate from truststore.

This issue occurs if the valid certificate is not present in the Trust Store and the latest certificate alias is not configured in Adobe Granite SAML 2.0 Authentication Handler. The browser will be in an infinite loop loading the URL for this issue

Follow the below steps to fix the issue.

Login to user admin through touch UI URL - http://localhost:4502/libs/granite/security/content/useradmin.html

Search for authentication-service and open it

Click on "Manage TrustStore"

Click on "Select Certificate File" and select the IDP public certificate


Click on Submit, this will upload the certificate to Trust Store



Copy the Alias and configure it in "Adobe Granite SAML 2.0 Authentication Handler"

Issue4:

14.05.2018 14:49:26.832 *INFO* [qtp1134377453-62] com.adobe.granite.auth.saml.SamlAuthenticationHandler Login failed. SAML token invalid.

This issue occurs if the saml:Audience value in SAML response is different than the Service Provider Entity ID value configured in the Adobe Granite SAML 2.0 Authentication Handler. The browser will be in an infinite loop loading the URL for this issue

As resolution sync the values between IDP and Adobe Granite SAML 2.0 Authentication Handler

The saml:Audience can be referred in SAML response, make sure the values are exactly matching.

<saml:Audience>http://xxxxxxxxxxxxxxx:4502</saml:Audience>

Issue5:

This issue occurs if the /etc/key folder is deleted by mistake or /etc/key folder is migrated from a different server.

Please note this issue will not occur immediately after deleting the /etc/key folder or uploading, the issue occurs only after the server is restarted post deletion or uploading of /etc/key .

Follow the below steps to fix the issue:

Create the /etc/key package from backup or from the publisher and upload it



Restart the server

Follow the below additional steps if the issue is not resolved

Login to crxde and delete the following nodes - '/etc/truststore/truststore.p12' and '/home/users/system/authentication-service/keystore/store.p12'.


Click Save All.

Follow the steps specified in Issue1 and Issue3 to initiate Trust/Key Store and to configure the IDP certificate.
