LDAP URLs provide a uniform method to access information on an LDAP server. Defined in RFC 2255, LDAP URLs begin with the prefix LDAP:// or LDAPS://. The following provides the syntax and descriptions of an LDAP URL.
ldap[s]://<hostname>:<port>/<base_dn>?<attributes>?<scope>?<filter>?<extension>
Note that ldaps is a common enhancement used to denote SSL, and is not defined in an RFC.
