;;; Commentary:

;;    This package provides basic functionality to perform searches on LDAP
;;    servers.  It requires a command line utility generally named
;;    `ldapsearch' to actually perform the searches.  That program can be
;;    found in all LDAP developer kits such as:
;;      - UM-LDAP 3.3 (http://www.umich.edu/~dirsvcs/ldap/)
;;      - OpenLDAP (http://www.openldap.org/)

Valid properties include:
  `binddn' is the distinguished name of the user to bind as

  `passwd' is the password to use for simple authentication.
  `auth' is the authentication method to use.
    Possible values are: `simple', `krbv41' and `krbv42'.
  `base' is the base for the search as described in RFC 1779.
  `scope' is one of the three symbols `subtree', `base' or `onelevel'.
  `deref' is one of the symbols `never', `always', `search' or `find'.
  `timelimit' is the timeout limit for the connection in seconds.

SEARCH-PLIST is a property list describing the search request.

will grab the :host, :secret, :base, and (:user or :binddn)
tokens into the `host', `passwd', `base', and `binddn' parameters

  machine ldapserver:2400 login myDN secret myPassword base myBase
  machine ldapserver:2400 binddn myDN secret myPassword port ldap

but if you have more than one in your netrc file, only the first

required.

  `host' is a string naming one or more (blank-separated) LDAP servers
to try to connect to.  Each host name may optionally be of the form HOST:PORT.
  `filter' is a filter string for the search as described in RFC 1558.
  `attributes' is a list of strings indicating which attributes to retrieve
for each matching entry. If nil, return all available attributes.
  `attrsonly', if non-nil, indicates that only attributes are retrieved,
not their associated values.
  `auth' is one of the symbols `simple', `krbv41' or `krbv42'.
  `base' is the base for the search as described in RFC 1779.
  `scope' is one of the three symbols `sub', `base' or `one'.
  `binddn' is the distinguished name of the user to bind as (in RFC 1779 syntax).
  `auth' is one of the symbols `simple', `krbv41' or `krbv42'
  `passwd' is the password to use for simple authentication.
  `deref' is one of the symbols `never', `always', `search' or `find'.
  `timelimit' is the timeout limit for the connection in seconds.
  `sizelimit' is the maximum number of matches to return.
  `withdn' if non-nil each entry in the result will be prepended with
its distinguished name DN.
The function returns a list of matching entries.  Each entry is itself
an alist of attribute/value pairs."
