 LDAP integration
 ================

+Overview
+--------
+
+Using LDAP as a source for user credentials and information is quite
+easy. The most difficult part lies in building an LDAP schema or
+using an existing one.
+
+At cube creation time, one is asked if more sources are wanted. LDAP
+is one possible option at this time. Of course, it is always possible
+to set it up later in the `source` configuration file, which we
+discuss there.
+
+It is possible to add as many LDAP sources as wanted, which translates
+in as many [ldapxxx] sections in the `source` configuration file.
+
+The general principle of the LDAP source is, given a proper
+configuration, to create local users matching the users available in
+the directory, deriving local user attributes from directory users
+attributes. Then a periodic task ensures local user information
+synchronization with the directory.
+
+Credential checks are _always_ done against the LDAP server.
+
+The base functionality for this is in
+cubicweb/server/sources/ldapuser.py.
+
+Configurations options
+----------------------
+
+Let us enumerate the options (but please keep in mind that the
+authoritative source for these is in the aforementioned python
+module), by categories (LDAP server connection, LDAP schema mapping
+information, LDAP source internal configuration).
+
+LDAP server connection options:
+
+* host: may contain port information using <host>:<port> notation.
+* protocol (choices are ldap, ldaps, ldapi)
+* auth-mode (choices are simple, cram_md5, digest_md5, gssapi, support
+  for the later being partial as of now)
+* auth-realm, realm to use when using gssapi/kerberos authentication
+* data-cnx-dn, user dn to use to open data connection to the ldap (eg
+  used to respond to rql queries)
+* data-cnx-password, password to use to open data connection to the
+  ldap (eg used to respond to rql queries)
+
+LDAP schema mapping:
+
+* user-base-dn, base DN to lookup for users
+* user-scope, user search scope
+* user-classes, classes of user
+* user-attrs-map, map from ldap user attributes to cubicweb attributes
+* user-login-attr, attribute used as login on authentication
+
+LDAP source internal configuration:
+
+* user-default-group, name of a group in which ldap users will be by
+  default. You can set multiple groups by separating them by a comma
+* synchronization-interval, interval between synchronization with the
+  ldap directory in seconds (default to once a day)
+* life time of query cache in minutes (default to two hours).
