I have the task to implement a accessibility to an Active Directory Federation Services (SSL) with a LDAP behind. At first I have to to say that my experience in ADFS and SAML is very small. I have decide to take the Spring Security SAML Extension to implement this feature. I download and install the SAML extension for the Spring Security project from GIThub: https://github.com/spring-projects/spring-security-saml
I found in the official documentation http://docs.spring.io/spring-security-saml/docs/1.0.x/reference/html/ under point "6. IDP integration guide" the instructions which I have all done.
- I download the metadata from the ADFS-Server
- I stored the downloaded metadata under saml2-sample/WEB-INF/src/main/resources/security/FederationMetadata.xml and enhance securityContext.xml how it is described
- After starting the web application the system generate automatically the metadata document
- I create a metadata.xml and gave it to the system administrator of the ADFS-server
- The system administrator make the rest of the points done.
After this I wanted test the Login. After I select the IDP and click at the Login-Button, I was asked for the credentials. After transmit the credentials I get the following result / exception:
- Evaluating security policy of type 'org.opensaml.ws.security.provider.BasicSecurityPolicy' for decoded message
- SAML protocol message was not signed, skipping XML signature processing
- Successfully decoded message.
- Checking SAML message intended destination endpoint against receiver endpoint
- Intended message destination endpoint: ........
- Actual message receiver endpoint: ........
- SAML message intended destination endpoint matched recipient endpoint
- Verifying issuer of the message
- Decrypting assertion
- Getting key iterator from next resolver: class org.opensaml.xml.encryption.InlineEncryptedKeyResolver
- Found matching encrypted key: org.opensaml.xml.encryption.impl.EncryptedKeyImpl@78f5b81e
- Added decryption key algorithm criteria: RSA
- Error decrypting the encrypted data element
org.apache.xml.security.encryption.XMLEncryptionException: Illegal key size
Original Exception was java.security.InvalidKeyException: Illegal key size
