>          Issue Type: Bug

> In case when customers using LdapExtLoginModule with option parseUsername=true but without option usernameBeginString (i.e. usernameBeginString=null) then all users cannot be successfully authenticated into application. Authentication failure is caused by hidden internal NPE.
> It is the same issue as was reported in [1], but fix is missing in current EAP 7.1 version of PicketBox (5.0.0.Alpha3).
> We request blocker flag because:
> * Valid configuration which works for 7.0.x becomes invalid after migration to 7.1.0
> * All users cannot authenticate to application despite of valid EAP configuration
> * Authetication failure caused by NPE is logged to server log
> Thrown NPE:
> {code}
> java.lang.NullPointerException
