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, on the AD FS server.
This section provides solutions to the basic problems, such as:
If you see the following error:
ERROR c.onelogin.saml2.authn.SamlResponse - Signature validation failed. SAML Response rejected
Then it means that the public key which you referred to in onelogin.saml.properties is not valid, that is:
onelogin.saml2.idp.x509cert =MIIC2DCCAcCgAwIBAgIQfdRAAWmWko1IsimA004o3TANBgkqhki…
You may see 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
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.
Here's a fix for this:
SAML requires the name 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:
Ensure that you pass the correct name ID and that it matches the format expected by the SAML bridge (that is, onelogin.saml2.sp.nameidformat of onelogin.saml.properties).
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';
The example below shows a list of correct Yellowfin logs regarding 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>
If you see the following error in your Yellowfin logs:
INFO (AdministrationService:remoteAdministrationCall) - WebserviceException caught: 8(COULD_NOT_FIND_PERSON)
Then it means that you have switched off the user provision functionality, and the passed ID is not of a Yellowfin user.
