/*
 * Extract components of an LDAP URL.

 * The format of an LDAP URL is defined in RFC 2255 as follows:
 *
 *     ldapurl    = scheme "://" [hostport] ["/"
 *                  [dn ["?" [attributes] ["?" [scope]
 *                  ["?" [filter] ["?" extensions]]]]]]
 *     scheme     = "ldap"
 *     attributes = attrdesc *("," attrdesc)
 *     scope      = "base" / "one" / "sub"
 *     dn         = distinguishedName from Section 3 of [1]
 *     hostport   = hostport from Section 5 of RFC 1738 [5]
 *     attrdesc   = AttributeDescription from Section 4.1.5 of [2]
 *     filter     = filter from Section 4 of [4]
 *     extensions = extension *("," extension)
 *     extension  = ["!"] extype ["=" exvalue]
 *     extype     = token / xtoken
 *     exvalue    = LDAPString from section 4.1.2 of [2]
 *     token      = oid from section 4.1 of [3]
 *     xtoken     = ("X-" / "x-") token
 *
 * For example,
 *
 *     ldap://ldap.itd.umich.edu/o=University%20of%20Michigan,c=US
 *     ldap://host.com:6666/o=IMC,c=US??sub?(cn=Babs%20Jensen)
 *
 * This class also supports ldaps URLs.
