Navigating to Entity ID gives 404 Error

[Nate Klingenstein]

Matt,

> Would this point back to an issue with the IDP-Metadata.xml? I apologize for the multiple questions, I'm new to SAML and it's been a steep learning curve. Looking in the logs I get the following.

It's no problem.  A willingness to learn and ask questions is the best asset you can have.  Your answer lies in your message and there's not much we can tell you beyond this:

2022-09-21 06:53:40,045 -  - ERROR [net.shibboleth.utilities.java.support.service.AbstractReloadableService:182] - Service 'shibboleth.MetadataResolverService': Initial load failed
net.shibboleth.utilities.java.support.service.ServiceException: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 81 in XML document from file [C:\Program Files (x86)\Shibboleth\IdP\conf\metadata-providers.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 81; columnNumber: 1; XML document structures must start and end within the same entity.

You've got something malformed in your XML and it's getting caught by the parser on line 81.  You can try an online validator or even SAMLtest for this one since it's an XML-level error and not a SAML schema error, or you can use a tool ilke xmllint, or whatever else you're comfortable using.

If you really can't spot the issue, feel free to send me a copy of your metadata off-list and I'll help you debug it.  I do that routinely for people using SAMLtest, which is upwards of 85,000 entities today.

Take care,
Nate
