Overview#

LDAP String Representation of Search Filters is defined in RFC 4515 Some applications may find it useful to have a common way of representing these search filters in a human-readable form.

LDAP URLs (RFC 4516) are an example of one such application.

RFC 4515 defines a human-readable string format for representing the full range of possible LDAP version 3 search filters, including extended match filters.

The Lightweight Directory Access Protocol (LDAP) RFC 4510 defines a network representation of a search filter transmitted to an LDAP server.
