22 * LDAP URLs look like this:
23 * ldap[is]://host[:port][/[dn[?[attributes][?[scope][?[filter][?exts]]]]]]
26 * attributes is a comma separated list
27 * scope is one of these three strings: base one sub (default=base)
28 * filter is an string-represented filter as in RFC 4515
30 * e.g., ldap://host:port/dc=com?o,cn?base?(o=openldap)?extension
32 * We also tolerate URLs that look like: <ldapurl> and <URL:ldapurl>
