The JDiagnostic User Source Checker provides a front end to the user source system. Typically the user source system is invoked when the SSO system wishes to automatically create a new user or when the synchronisation system wishes to update the details of a user.

The User Source Checker accepts a username (which can be obtained from the SSO Checker) to attempt to find details from. Optionally the system can be instructed to attempt autocreation on the local site which would happen if the user didn't exist normally. The default is just to display the result of the operations and any potential errors, however autocreating the user may also raise other errors not detected by JDiagnostic.

In this example the LDAP user source plugin has used the username 'moffats' to find the correct username and email address. Also keep in mind that user source plugins can suggestif a user should be blocked or should be in a specific type. In this case there were no errors detected with the user so it should be fine to autocreate the user.
