   Parameters are  

   ld              LDAP pointer to the desired connection 

   authzid		   RFC2829 section 9, eg "dn:<DN>".
                   NULL or empty string means get bound user's rights,

   attrlist        additional attributes for which rights info is 
                   requrested. NULL means "just the ones returned 
                   with the search operation".

   ctl_iscritical  Indicates whether the control is critical of not. If
                   this field is non-zero, the operation will only be car-
