+ * LIBLDAP url.c -- LDAP URL (RFC 2255) related routines
*
* LDAP URLs look like this:
- * l d a p : / / hostport / dn [ ? attributes [ ? scope [ ? filter ] ] ]
+ * ldap[s]://host:port[/[dn[?[attributes][?[scope][?[filter][?exts]]]]]]
*
* where:
* attributes is a comma separated list
* scope is one of these three strings: base one sub (default=base)
- * filter is an string-represented filter as in RFC 1558
+ * filter is an string-represented filter as in RFC 2254
*
- * e.g., ldap://ldap.itd.umich.edu/c=US?o,description?one?o=umich
+ * e.g., ldap://host:port/dc=com?o,cn?base?o=openldap?extension
*
* We also tolerate URLs that look like: <ldapurl> and <URL:ldapurl>
