       These routines support the use of LDAP URLs (Uniform Resource Locators)
       as detailed in RFC 4516.  LDAP URLs look like this:


         hostport is a host 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 is filter
         exts are recognized set of LDAP and/or API extensions.


       URLs  that  are wrapped in angle-brackets and/or preceded by "URL:" are
       also tolerated.  Alternative LDAP 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 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 a
       more thorough check is needed.

       ldap_url_parse() breaks down  an  LDAP  URL  passed  in  url  into  its
       component  pieces.   If  successful,  zero  is  returned,  an  LDAP URL
       description is allocated, filled in, and ludpp is set to point  to  it.
       If an error occurs, a non-zero URL error 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().
