Using Wildfly 8.1.0.Final
I want to create a web app that requires basic authentication for access to /api/* but the rest of the application should be open. To accomplish this I have the following web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
<security-constraint>
<web-resource-collection>
<web-resource-name>Api access</web-resource-name>
<url-pattern>/api/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>api</role-name>
</auth-constraint>
</security-constraint>
<security-role>
<role-name>api</role-name>
</security-role>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Authentication requires api access</realm-name>
</login-config>
</web-app>
Testing with a browser, this works as expected.
http://localhost:8080/myapp/api
...requires authentication.
http://localhost:8080/myapp
...does not require authentication.
Here comes the tricky part:
A third party accesses /myapp and includes an authorization header in the request:
Authorization: Basic ZGlsbDpkYWxs
This is not a user registered in wildfly, but that shouldnt matter because /myapp is open, and does not require authorization. However what happens is this:
401 Unauthorized
Why? I have not told undertow to use any security constraints for /myapp, yet it defaults to the security constraints I have registered for /myapp/api
This is new behaviour that was introduced with undertow, because with Jboss AS 7.1.1.Final this did not happen.
How can I tell undertow to not use authorization for an open resource when authorization is included in the request?
