Error with IIS Native SP

[Boyd, Todd M.]

I'm trying to set up the IIS Native SP and get it talking with our IdP. I had it working at one point about a month ago, but for reasons outside of my control, that configuration is now gone. When I try to log into the protected /secure path on my SP server, I get this error message:

	An unexpected error was encountered, usually reflecting a configuration or software error.

Looking in the debug logs for the IdP, I see this:

	2017-09-25 12:45:46,161 - WARN [net.shibboleth.ext.spring.context.FilesystemGenericApplicationContext:549] - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'shibboleth.UnverifiedRelyingParty' defined in file [C:\Program Files (x86)\Shibboleth\IdP\conf\relying-party.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.beans.factory.BeanExpressionException: Expression parsing failed; nested exception is org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 0): Property or field 'ShibServerName' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' - maybe not public?

Could anyone help me with what that actually *means*? I'm using a file-backed HTTP metadata endpoint for the SP.


Thanks,
