For troubleshooting, it is better to run the SSO URL provided by onelogin.saml2.idp.single_sign_on_service.url of the onelogin.saml.properties. Ideally, ideally, on the AD FS server.

This section provides solutions to the basic problems, such as:

• Signature validation failed
• Illegal key size
• Invalid name ID
• Person not found

Signature validation failed

You may If you see the following error like:

ERROR c.onelogin.saml2.authn.SamlResponse - Signature validation failed. SAML Response rejected

That Then it means that the public key which you refer referred to in onelogin.saml.properties is not valid, that is:

onelogin.saml2.idp.x509cert =MIIC2DCCAcCgAwIBAgIQfdRAAWmWko1IsimA004o3TANBgkqhki…

Solution

...

• Get a valid certificate from AD FS;
• modify onelogin.saml.properties (onelogin.saml2.idp.x509cert);
• restart Yellowfin;
• update Yellowfin SAML Bridge relying party metadata in AD FS.

Illegal Key Size

You may see this the following exception in the Yellowfin logs:

org.apache.xml.security.encryption.XMLEncryptionException: Illegal key size

The Original Exception was java.security.InvalidKeyException: Illegal key size

Solution

...

When inspecting the SAML response payload below, the data is encrypted with AES-256:

Refer to the EncryptionMethod Algorithm ="here: http://www.w3.org/2001/04/xmlenc#aes256-cbc"

 

By default, Java’s key size is limited to 128-bit key due to US export laws and a few countries’ import laws.

To fixHere's a fix for this:

• Download Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files:
  Java 7: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html
  Java 8: http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

• Copy the local_policy.jar and US_export_policy.jar files to this directory: [JAVA_HOME]/jre/lib/security.

Invalid Name ID

SAML requires the name id ID as part of the Identity Provider response. If you provide the incorrect name ID of your AD FS, then you will see the following exception in your browser something like:

You do not pass correct name id from AD FS. Ensure that you pass the correct name id from AD FS and the name id ID and that it matches the format which expected by the SAML bridge expects (that is, onelogin.saml2.sp.nameidformat of onelogin.saml.properties).

Possible Here's a list of possible formats:

NAMEID_EMAIL_ADDRESS = 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress';

NAMEID_X509_SUBJECT_NAME = 'urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName';

NAMEID_WINDOWS_DOMAIN_QUALIFIED_NAME = 'urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName';

NAMEID_UNSPECIFIED = 'urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified';

NAMEID_KERBEROS   = 'urn:oasis:names:tc:SAML:2.0:nameid-format:kerberos';

NAMEID_ENTITY     = 'urn:oasis:names:tc:SAML:2.0:nameid-format:entity';

NAMEID_TRANSIENT  = 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient';

NAMEID_PERSISTENT = 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent';

NAMEID_ENCRYPTED = 'urn:oasis:names:tc:SAML:2.0:nameid-format:encrypted';

Correct The example below shows a list of correct Yellowfin logs regarding to the SAML response:

DEBUG c.onelogin.saml2.authn.SamlResponse - SAMLResponse validated --> …

…

DEBUG c.onelogin.saml2.authn.SamlResponse - SAMLResponse has NameID --> john.smith@yellowfin.bi

DEBUG c.onelogin.saml2.authn.SamlResponse - SAMLResponse has attributes: {http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress=[john.smith@yellowfin.bi]}

DEBUG com.onelogin.saml2.SamlAuth - processResponse success --> <very long line representing signing certificate>

...

COULD_NOT_FIND_PERSON

If you see this the following error in your Yellowfin logs:

INFO (AdministrationService:remoteAdministrationCall) - WebserviceException caught: 8(COULD_NOT_FIND_PERSON)

That Then it means that you have switched off the user provision off and this id functionality, and the passed ID is not of a Yellowfin user.
