Multiple Principal not working - JBoss 4.2.1

[jbosexplorer]

Hi There,

I'm using JBoss 4.2.1 and doing LDAP Authentication (j_security_check) in my web application. I've the following snippet in web.xml

<security-role>
 <role-name>Admin_View</role-name>
 </security-role>
<security-role>
 <role-name>AdminStandard</role-name>
 </security-role>...

and, the following in jboss-web.xml.

<security-role>
 <role-name>Admin_View</role-name>
 <principal-name>AdminStandard</principal-name>
 <principal-name>AdminAuthoriser</principal-name>
 <principal-name>AdminSuperUser</principal-name>
 </security-role>

In my java code, I'm doing the following for a user in AdminStandard group in LDAP,

if(this.getRequest().isUserInRole("Admin_View"))
 {
 forward = "adminsuccess";
 }

it's not going thru' the loop. when I debugged, the condn returns false. any idea why?

Thanks.
