Hi,

I have installed Jenkins ver. 2.176.2 war as an application within my WebLogic Server (12.2.1.3). It's working as expected for all my other needs. I want to integrate with ADFS using SAML 2.0 and that's where I am running into issues. I have downloaded and installed the SAML Plugin (v 1.1.2). When I enable the SAML checkbox and enter the IDP Metadata Content or IDP MetaData URL and click on "Validate IDP MetaData" I get error message as shown below. 

Appreciate your help in this regards.

Thanks
