Configure SAML SSO for GlobalProtect

[alemonnier]

Hello,

I'm trying to configure GP with SAML/SSO Auth. After entering credentials I get a "Authentication FailedError code: -1" using GP web portal.

On SAML server side the authent is OK.

It seems like the FW doesn't like the response from the server. 

It tries to verify the Idp signature but I didn't select this option...

Issue solved 

On server side (Keycloak), parameter "SAML Signature Key Name" was configured on "KEY_ID" instead of "CERT_SUBJECT".

I don't know if it's possible to add it in metadata file? Because that not written anywhere....

If that can help someone 🙂
