Hello,

I'm trying to migrate an application from WildFly 8 to 10. After migration PicketLink SSO Federation stopped work properly. I'm got this error after redirection from Identity Provider to Service Provider.

19:04:05,926 DEBUG [org.jboss.security] (default task-17) PBOX00206: Login failure: javax.security.auth.login.LoginException: unable to find LoginModule class: org.picketlink.identity.federation.bindings.jboss.SAML2LoginModule from [Module "deployment.mca-web.war:main" from Service Module Loader]

It looks like an issue caused by PicketLink version downgrade on WildFly 10.

I tried to change SP login module from:

<login-module code="org.picketlink.identity.federation.bindings.wildfly.SAML2LoginModule" flag="required"/>

to

<login-module code="org.picketlink.identity.federation.bindings.jboss.SAML2LoginModule" flag="required"/>

But it doesn't has effect.

I would appreciate any help

Thanks
