SHIBBOLETH SP - Shibboleth handler invoked at an unconfigured location - Shibboleth.sso/Session/

I am trying to get shibboleth configured. When I go to https://mysite/secure/index.php, it works properly, I can authenticate, etc. but when I go to https://mysite/Shibboleth.sso/Status (or any other https://mysite/Shibboleth.sso/*) I get the following message:

shibsp::ConfigurationException

The system encountered an error at Mon Jul 10 12:06:32 2017

To report this problem, please contact the site administrator at root@localhost.

Please include the following message in any email:

shibsp::ConfigurationException at (https://mysite/Shibboleth.sso/Session/)

Shibboleth handler invoked at an unconfigured location.

My shibboleth2.xml is as follows (comments removed for brevity):

I have examined every config file I can find, every setting I can think of. I turned on debug mode for native.logger and shibd.logger but not found anything.

What is wrong? or where should I look?

The problem was actually with the way Apache is configured. It was rewriting urls to add a / at the end of each url. so https://mysite/Shibboleth.sso/Session became https://mysite/Shibboleth.sso/Session/. It is always the minor things!

Since the Apache configuration is necessary for another portion of the project, I changed the Location attribute to add a slash at the end and it worked perfectly! HT- Scott Cantor on Users@shibboleth.net mailing list!
