Darran Lofthouse commented on SECURITY-476:
-------------------------------------------

> Hi , we ran into similar problem similar problem with domain qualified principals and AdvancedLdapLoginModule while working with JBOSS EAP 4.3 , queries to AD failed 
> since sAMAccountName doesn't include the domain part.

When using the AdvancedLdapLoginModule chained after the SPNEGOLoginModule you should use the following baseFilter to locate the user: -

         <module-option name="baseFilter">(userPrincipalName={0})</module-option>

The userPrincipalName field in Active Directory contains the full name in the form name at REALM

> We have a legacy application which already uses authentication but cannot handle the realm part of the principal name. To enable single sign on we have made the changes in provided patch which allows to configure the module-option cutOffDomain for SPNEGOLoginModule. If the username ends with the realm name configured in this option the realm name is removed from the user name. This way the application gets the simpler name in the HttpServletRequest. Principals not ending with this realm are left untouched.
