Single Sign On (SSO) no JBoss AS 7.1.1

Front-end
#1

Feras,

estou configurando Single Sign On (SSO) no JBoss AS 7.1.1 seguindo os passos que encontrei no link abaixo

https://jbossdivers.wordpress.com/2012/05/23/configurando-single-sign-on-sso-no-jboss-as-7-1-1/

porém quando acesso a aplicação logo a mesma me solicita a usuário e senha, minha aplicação esta validando essas informações no AD,

mas quando coloco as credenciais do AD a aplicação gera o erro abaixo, alguém pode ajudar ?
