[mitreid-connect] Custom AuthenticationProvider

Tue Jun 6 18:21:50 EDT 2017

I’ve found the method-not-allowed message from Spring to be misleading.  That’s likely due to missing a CSRF on the login form, but the LDAP overlay shouldn’t have any customizations there.

For one, if you’ve got your auth manager in with “alias” instead of “id”, it can fail in weird ways. Also note that the field names for username and password, as well as the username/password filter, have all changed by default. The other issues had to do with the default session and CSRF behavior in the new version of spring, but that shouldn’t affect the initial login.

The login page shows up but it always fails even with proper username and password (obviously as the authentication provider is not being called). Nothing in the logs at info level and couldn’t find anything useful in debug. Interesting that when I try using a previous MitreID 1.2.x that we have it works. Maybe something new with 1.3.x?

For that I’ve been trying to implement a custom authentication provider but so far couldn’t make it to work. The constructor is called but neither supports nor authenticate methods are. Using an overlay project for that, overriding user-context.xml with the security:authentication-provider setting pointing to our custom provider. As far as I can see, our project is very similar to the LDAP overlay.
