Bug 653007 - db2ldif export of clear text passwords lacks storage scheme
    
    https://bugzilla.redhat.com/show_bug.cgi?id=653007
    
    Description: Export utility db2ldif{.pl} used to export clear
    text passwords without the storage scheme name {CLEAR}.
    This patch checks each userPassword value.  If the value is
    not hashed, put "{CLEAR}" in front of the value as follows.
        userPassword: {CLEAR}notsosecret
