DESCRIPTION         top

       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().
