I'm trying to setup the SSO in Zoom with my Gluu server, but in the Trust Relationship it fails when I upload the metadata file and it has this errors: **Error of schema creating schema_reference.4: Failed to read schema document 'http://shibboleth.net/schema/idp/shibboleth-resource.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. Warning: cannot validate metadata. Check internet connetion ans www.w3.org availability. Warning: Error of schema creating Warning: schema_reference.4: Failed to read schema document 'http://shibboleth.net/schema/idp/shibboleth-resource.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.** I followed the instructions listed here: **https://support.zoom.us/hc/en-us/articles/201363003-Getting-Started-with-SSO** and they say this: **First, configure your IdP to send us the following Any unique identifier linked to nameID such as edupersonTargetedID, persistentID or mail** So I added a NameID with the attribute PersistentId as I show in the attachments. And finally I got the SP metadata from Gluu, as it's shown in the attachments. You can find the attachments [here](https://mega.nz/folder/TBgTUJqa#F2QoQ1Ovy10zZiQTlwGKNA). Please, could you tell me what I am doing wrong?
