Hi,

I've made a smaller standalone Java app that has this same code plus 
some addition printlns in the catch, and the following is the stack 
trace that I'm getting:

  In getPwdLastSet(): ** ERROR **: LDAP search for 'pwdLastSet' failed ...
  In getPwdLastSet(): ** ERROR **: 
LDAPReferralException.getLDAPErrorMessage(): [
Referral:
ldap://whatever.com/CN=Configuration,DC=whatever,DC=com]
  In getPwdLastSet(): ** ERROR **: This MAY BLOW UP NOW...
Exception in thread "main" java.lang.NullPointerException
