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

authentication-service

Click on "Create KeyStore"
Enter password and click OK

aem-key-store


Click on "Create TrustStore"
Enter password and click OK

aem-trust-store

Issue2:

saml-authentication-handler-forbidden


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 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"

apache-sling-referrer-filter

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 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

aem-trust-store-certificate

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

aem-trust-store-certificate


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

cert_alias_saml_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 infinite loop loading the URL for this issue

As a 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>
