You can retrieve entityID by generating an xml file from SAML Metadata in Auth0:
1. Once you are logged in to Auth0, as seen in the screenshot below, scroll down until you see “Show Advance Setting”, click on it.
2. Then, scroll down until you see the field “SAML Metadata URL”(See below)
3. Open the browser and paste the copied URL into the browser. It will generate an xml file.
4. Open the xml file and look for Entity ID as shown below:
5. Make sure the “SAML Service Provider Name” field in your Artifactory instance matches the Entity_ID from xml file
