I am trying to set up my Active Directory configuration for this web application and it doesn't seem to be working. Maybe someone can help me...

Here is where my users are located:

msunet2k.edu
 Academic
 COE
 User

Here is where my group is that has what users I want to use this app:

msunet2k.edu
 Academic
 COE
 User
 Web Groups
 COE_GG_WEB_KATE (actual name of group)

Here is what I currently have in my login-config.xml file:

 <application-policy name="kwormSecurity">
 <authentication>
 <login-module code="org.jboss.security.auth.spi.LdapLoginModule" flag="required" >
 <module-option name="java.naming.provider.url">ldap://drawbridge.msunet2k.edu</module-option>
 <module-option name="rolesCtxDN">ou=User,ou=COE,ou=Academic,dc=msunet2k,dc=edu</module-option>
 <module-option name="matchOnUserDN">false</module-option>
 <module-option name="principalDNSuffix">@msunet2k.edu</module-option>
 <module-option name="principalDNPrefix">userPrincipalName</module-option>
 <module-option name="uidAttributeID">userPrincipalName</module-option>
 <module-option name="roleAttributeID">memberOf</module-option>
 <module-option name="roleAttributeIsDN">true</module-option>
 <module-option name="roleNameAttributeID">name</module-option>
 </login-module>
 </authentication>
 </application-policy>

Am I missing something?
