       These routines support the use of LDAP URLs (Uniform Resource Locators)
       as detailed in(1,8) RFC 2255.  LDAP URLs look(1,8,3 Search::Dict) like this:

         ldap://hostport/dn[?attrs[?scope[?filter(1,3x,3x curs_util)[?exts]]]]

         hostport is a host(1,5) name with an optional ":portnumber"
         dn is the search base
         attrs is a comma separated list of attributes to request
         scope is one of these three strings:
           base one sub (default=base)
         filter(1,3x,3x curs_util) is filter(1,3x,3x curs_util)
         exts are recognized set(7,n,1 builtins) of LDAP and/or API extensions.


       URLs  that  are wrapped in(1,8) angle-brackets and/or preceded by "URL:" are
       also tolerated.  Alternative schemes such as ldaps:// and ldapi://  may
       be parsed using the below routines as well.

       ldap_is_ldap_url()  returns  a non-zero value if(3,n) url looks like an LDAP
       URL (as opposed to some other kind of URL).  It can be used as a  quick
       check for an LDAP URL; the ldap_url_parse() routine should be used if(3,n) a
       more thorough check is needed.

       ldap_url_parse() breaks down an LDAP URL passed in(1,8) url into its  compo-
       nent  pieces.  If successful, zero is returned, an LDAP URL description
       is allocated, filled in(1,8), and ludpp is set(7,n,1 builtins) to point to it.  If an  error(8,n)
       occurs, a non-zero URL error(8,n) code is returned.

       ldap_free_urldesc()  should  be  called to free an LDAP URL description
       that was obtained from a call to ldap_url_parse().
