Glassfish4 : Realm waffle.apache.WindowsRealm is not an instance of com.sun.web.security.RealmAdapter, and will be ignored

[AniWar]

I'm using waffle mixed-authentication on Glassfish4 , I managed to change the waffle-tomcat jar to comply with web-core jar present in Glassfish . However , Glassfish does not treat 'waffle.apache.WindowsRealm' as proper realm , and ignores the authentication done by it , therefore I feel it restricts the resources . Is there any solution for this ?

The mixed authenticator as is was for Tomcat AFAIK, looks like you're on the right track making code changes for it to work for Glassfish. I would make/wrap WindowsRealm a/into a com.sun.web.security.RealmAdapter and see whether you get any further.
