We are getting an error when we test our SAML connection:

SAML 2.0 based Single Sign-On

Error when processing authentication request!

Please try login again!

 

When using tools to get a more detailed response we get:

ALERT: Invalid Assertion Consumer URL value 'https://www.lucidchart.com/saml/sso/macalester.edu' in the AuthnRequest message from the issuer 'lucidchart.com'. Possibly an attempt for a spoofing attack

 

From our metadata.xml:

<md:AssertionConsumerService isDefault="true" Binding="urn:oasis:names🇹🇨SAML:2.0:bindings:HTTP-POST" Location="https://admin.lucid.app/saml/sso/macalester.edu" index="0" />
 

How can we fix this?

Hi @ajohns34 !

Thank you for posting in the Lucid Community! 

Can you ensure that your Primary Assertion Consumer URL value matches the following format in both your IDP and your Lucid Admin Panel? https://lucid.app/saml/sso/<yourdomain>.  Here is our documentation on configuring SAML for your Account, I suggest reviewing your SAML configuration against the requirements from this article and testing once more. 

Please let me know if this issue persists, I’m happy to help!
