No MetadataProvider available - shibsp::ConfigurationException

Question

I recently upgraded Shibboleth from versionShibboleth-sp-2.5.6.0-win64 to Shibboleth-sp-2.6.0.0-win64 and Apache web server from 2.4.16 to 2.4.23.

Post the upgrade, when I try to access my application I get the following error:

shibsp::ConfigurationException

The system encountered an error at Fri Oct 14 20:19:51 2016

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

Please include the following message in any email:

shibsp::ConfigurationException at (https://xxxxxx.xxxx/)

No MetadataProvider available.

When I access, https:/xxxxx.xxxxx/Shibboleth.sso/Metadata, the metadata file is downloaded and the details seems correct.

Does any one know why does this error occur and how can we solve it?

Answer 1

If it can be of help, I was writing this:

<MetadataProvider type="XML" validate="true" file="/etc/shibboleth/idp-metadata.xml" />

instead of this:

<MetadataProvider type="XML" validate="true" path="/etc/shibboleth/idp-metadata.xml" />

The XML attribute is path. I'm using Shibboleth SP version 3.
