;;; 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/)

PROPn and VALn are property/value pairs describing parameters for the server.

Valid properties include:

`binddn' is the distinguished name of the user to bind as

(in RFC 1779 syntax).
|
|
`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.

`sizelimit' is the maximum number of matches to return."

"Perform a search on a LDAP server.
|
|
SEARCH-PLIST is a property list describing the search request.
|
|
Valid keys in that list are:
|
|
|
|
`auth-source', if non-nil, will use `auth-source-search' and
|
|
will grab the :host, :secret, :base, and (:user or :binddn)
|
|
tokens into the `host', `passwd', `base', and `binddn' parameters
|
|
respectively if they are not provided in SEARCH-PLIST. So for
|
|
instance *each* of these netrc lines has the same effect if you
|
|
ask for the host \"ldapserver:2400\":
|
|
|
|
machine ldapserver:2400 login myDN secret myPassword base myBase
|
|
machine ldapserver:2400 binddn myDN secret myPassword port ldap
|
|
login myDN secret myPassword base myBase
|
|
|
|
but if you have more than one in your netrc file, only the first
|
|
matching one will be used. Note the \"port ldap\" part is NOT
|
|
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).
|
|
`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."
