|
||||
\label{sec:ldap}
|
||||
\ind{modules!\modvcardldap{}}\ind{JUD}\ind{Jabber User Directory}\ind{vCard}\ind{protocols!JEP-0054: vcard-temp}
|
||||
|
||||
|
||||
\subsubsection{Features}
|
||||
\label{sec:ldapfeatures}
|
||||
|
||||
\ejabberd{} has built-in LDAP support. You can authenticate users against LDAP
|
||||
server and use LDAP directory as vCard storage. Shared rosters are not
|
||||
supported yet.
|
||||
|
||||
|
||||
\subsubsection{Connection}
|
||||
\label{sec:ldapconnection}
|
||||
|
||||
Parameters:
|
||||
|
||||
\begin{description}
|
||||
\titem{ldap\_server} \ind{options!ldap_server}IP address or dns name of your
|
||||
LDAP server. This option is required.
|
||||
\titem{ldap\_port} \ind{options!ldap_port}Port to connect to LDAP server.
|
||||
Default is~389.
|
||||
\titem{ldap\_rootdn} \ind{options!ldap_rootdn}Bind DN. Default is~\term{""}
|
||||
which means anonymous connection.
|
||||
\titem{ldap\_password} \ind{options!ldap_password}Bind password. Default
|
||||
is~\term{""}.
|
||||
\end{description}
|
||||
|
||||
Example:
|
||||
\begin{verbatim}
|
||||
{auth_method, ldap}.
|
||||
{ldap_servers, ["ldap.mydomain.org"]}.
|
||||
{ldap_port, 389}.
|
||||
{ldap_rootdn, "cn=Manager,dc=domain,dc=org"}.
|
||||
{ldap_password, "secret"}.
|
||||
\end{verbatim}
|
||||
|
||||
Note that current LDAP implementation doesn't support SSL connection and SASL
|
||||
authentication.
|
||||
|
||||
|
||||
\subsubsection{Authentication}
|
||||
\label{sec:ldapauthentication}
|
||||
|
||||
You can authenticate users against LDAP directory. Available parameters are
|
||||
listed below:
|
||||
|
||||
\begin{description}
|
||||
\titem{ldap\_base} \ind{options!ldap_base}LDAP base directory which stores users
|
||||
accounts. This option is required.
|
||||
\titem{ldap\_uidattr} \ind{options!ldap_uidattr}LDAP attribute which holds
|
||||
user's part of JID. Default is \term{"uid"}.
|
||||
\titem{ldap\_uidattr\_format} \ind{options!ldap_uidattr_format}Format of the
|
||||
\term{ldap\_uidattr} variable. Format MUST contain one and only one pattern
|
||||
variable \term{"\%u"} which will be replaced by user's part of JID. For example,
|
||||
\term{"\%u@mydomain.org"}. Default value is \term{"\%u"}.
|
||||
\titem{ldap\_filter} \ind{options!ldap_filter}RFC 2254 LDAP filter. Default is
|
||||
\term{none}. Example: \term{"(\&(objectClass=shadowAccount)(memberOf=Jabber
|
||||
Users))"}. Please, don't forget closing brackets and don't use superfluous
|
||||
whitespaces. Also you MUST NOT use \option{ldap\_uidattr} attribute in filter
|
||||
because this attribute will be substituted in LDAP filter automatically.
|
||||
\end{description}
|
||||
|
||||
|
||||
\subsubsection{vCards and Search}
|
||||
\label{sec:modvcardldap}
|
||||
|
||||
\ejabberd{} can map LDAP attributes to vCard fields. This behaviour is
|
||||
implemented in \modvcardldap{} module. This module doesn't depend on
|
||||
authentication method. \modvcardldap{} module has it's own optional
|
||||
parameters. The first group of parameters has the same meaning as top-level
|
||||
LDAP parameters: \option{ldap\_servers}, \option{ldap\_port},
|
||||
\option{ldap\_rootdn}, \option{ldap\_password}, \option{ldap\_base},
|
||||
\option{ldap\_uidattr}, \option{ldap\_uidattr\_format} and
|
||||
\option{ldap\_filter}. If one of this option is not set \ejabberd{} will look
|
||||
for top-level option with the same name. The second group of parameters
|
||||
consists of the following options:
|
||||
|
||||
\begin{description}
|
||||
\hostitem{vjud}
|
||||
\iqdiscitem{\ns{vcard-temp}}
|
||||
\titem{search} \ind{options!search}This option specifies whether the search
|
||||
functionality is enabled (value: \term{true}) or disabled
|
||||
(value: \term{false}). If disabled, the option \term{hosts} will be
|
||||
ignored and the \Jabber{} User Directory service will not appear in the
|
||||
Service Discovery item list. The default value is \term{true}.
|
||||
\titem{ldap\_vcard\_map} \ind{options!ldap_vcard_map}the table which defines
|
||||
reflection of LDAP attributes to vCard fields.
|
||||
Format is:
|
||||
\term{[{Name\_of\_vcard\_field, Pattern, List\_of\_LDAP\_attributes}, ...]}
|
||||
where
|
||||
\term{Name\_of\_vcard\_field} is the type name of vCard as defined
|
||||
in RFC 2426,
|
||||
Pattern is a string which contains pattern variables \term{"\%u"}, \term{"\%d"} or \term{"\%s"},
|
||||
\term{List\_of\_LDAP\_attributes} is the list which contains of LDAP attributes.
|
||||
Pattern variables \term{"\%s"} will be sequentially replaced with the values of
|
||||
LDAP attributes from \term{List\_of\_LDAP\_attributes}; \term{"\%u"} will be replaced with
|
||||
user's part of JID and \term{"\%d"} will be replaced with domain part of JID.
|
||||
Example:
|
||||
\begin{verbatim}
|
||||
{ldap_vcard_map,
|
||||
[{"NICKNAME", "%u", []},
|
||||
{"FN", "%s", ["displayName"]},
|
||||
{"CTRY", "Russia", []},
|
||||
{"EMAIL", "%u@%d", []},
|
||||
{"DESC", "%s\n%s", ["title", "description"]}
|
||||
]},
|
||||
\end{verbatim}
|
||||
|
||||
Default is:
|
||||
\begin{verbatim}
|
||||
[{"NICKNAME", "%u", []},

{"FN", "%s", ["displayName"]},
|
||||
{"FAMILY", "%s", ["sn"]},

|
||||
{"ROLE", "%s", ["employeeType"]},
|
||||
{"PHOTO", "%s", ["jpegPhoto"]}]
|
||||
\end{verbatim}
|
||||
\titem{ldap\_search\_fields} \ind{options!ldap_search_fields}This option defines
|
||||
search form and LDAP attributes to search.
|
||||
Format:
|
||||
\term{[{Name, Attribute}, ...]}
|
||||
where
|
||||
\term{Name} is the name of field in the search form. Will be automatically
|
||||
translated according to definitions in translation files (see
|
||||
\term{msgs/*.msg} for available words).
|
||||
Attribute is the LDAP attribute or the pattern \term{"\%u"}
|
||||
Example:
|
||||
\begin{verbatim}
|
||||
{ldap_search_fields,
|
||||
[{"User", "uid"},
|
||||
{"Full Name", "displayName"},
|
||||
{"Email", "mail"}
|
||||
]},
|
||||
\end{verbatim}
|
||||
|
||||
Default is:
|
||||
\begin{verbatim}
|
||||
[{"User", "%u"},
|
||||
{"Full Name", "displayName"},
|
||||
{"Given Name", "givenName"},

||||
Format:
|
||||
\term{[{Name, VCard\_Name}, ...]}
|
||||
where
|
||||
\term{Name} is the name of field in the search form. Will be automatically
|
||||
translated according to definitions in translation files (see
|
||||
\term{msgs/*.msg} for available words).
|
||||
\term{VCard\_Name} is the name of vCard field defined in \option{ldap\_vcard\_map} option.
|
||||
Example:
|
||||
\begin{verbatim}

\subsubsection{Examples}
|
||||
\label{sec:ldapexamples}
|
||||
|
||||
\paragraph{Common example}
|
||||
|
||||
Let's say \term{ldap.mydomain.org} is the name of our LDAP server. We have
|
||||
users with their passwords in \term{"ou=Users,dc=mydomain,dc=org"} directory.
|
||||
Also we have addressbook, which contains users emails and their additional
|
||||
infos in \term{"ou=AddressBook,dc=mydomain,dc=org"} directory. Corresponding
|
||||
authentication section should looks like this:
|
||||
|
||||
\begin{verbatim}
|
||||
%% authentication method
|
||||
{auth_method, ldap}.
|
||||
%% DNS name of our LDAP server
|
||||
{ldap_servers, ["ldap.mydomain.org"]}.
|
||||
%% Bind to LDAP server as "cn=Manager,dc=mydomain,dc=org" with password "secret"
|
||||
{ldap_rootdn, "cn=Manager,dc=mydomain,dc=org"}.
|
||||
{ldap_password, "secret"}.
|
||||
%% define the user's base
|
||||
{ldap_base, "ou=Users,dc=mydomain,dc=org"}.
|
||||
%% We want to authorize users from 'shadowAccount' object class only
|
||||
{ldap_filter, "(objectClass=shadowAccount)"}.
|
||||
\end{verbatim}
|
||||
|
||||
Now we want to use users LDAP-info as their vCards. We have four attributes
|
||||
defined in our LDAP schema: \term{"mail"} --- email address, \term{"givenName"}
|
||||
--- first name, \term{"sn"} --- second name, \term{"birthDay"} --- birthday.
|
||||
Also we want users to search each other. Let's see how we can set it up:
|
||||
|
||||
\begin{verbatim}
|
||||
{modules,
|
||||
...
|
||||
{mod_vcard_ldap,
|
||||
[
|
||||
%% We use the same server and port, but want to bind anonymously because
|
||||
%% our LDAP server accepts anonymous requests to
|
||||
%% "ou=AddressBook,dc=mydomain,dc=org" subtree.
|
||||
{ldap_rootdn, ""},
|
||||
{ldap_password, ""},
|
||||
%% define the addressbook's base
|
||||
{ldap_base, "ou=AddressBook,dc=mydomain,dc=org"},
|
||||
%% user's part of JID is located in the "mail" attribute
|
||||
{ldap_uidattr, "mail"},
|
||||
%% common format for our emails
|
||||
{ldap_uidattr_format, "%u@mail.mydomain.org"},
|
||||
%% We have to define empty filter here, because entries in addressbook doesn't
|
||||
%% belong to shadowAccount object class
|
||||
{ldap_filter, ""},
|
||||
%% Now we want to define vCard pattern
|
||||
{ldap_vcard_map,
|
||||
[{"NICKNAME", "%u", []}, % just use user's part of JID as his nickname
|
||||
{"GIVEN", "%s", ["givenName"]},
|
||||
{"FAMILY", "%s", ["sn"]},
|
||||
{"FN", "%s, %s", ["sn", "givenName"]}, % example: "Smith, John"
|
||||
{"EMAIL", "%s", ["mail"]},
|
||||
{"BDAY", "%s", ["birthDay"]}]},
|
||||
%% Search form
|
||||
{ldap_search_fields,
|
||||
[{"User", "%u"},
|
||||
{"Name", "givenName"},
|
||||
{"Family Name", "sn"},
|
||||
{"Email", "mail"},
|
||||
{"Birthday", "birthDay"}]},
|
||||
%% vCard fields to be reported
|
||||
%% Note that JID is always returned with search results
|
||||
{ldap_search_reported,
|
||||
[{"Full Name", "FN"},
|
||||
{"Nickname", "NICKNAME"},
|
||||
{"Birthday", "BDAY"}]}
|
||||
]}
|
||||
...
|
||||
}.
|
||||
\end{verbatim}
|
||||
|
||||
Note that \modvcardldap{} module checks an existence of the user before
|
||||
searching his info in LDAP.
|
||||
|
||||
|
||||
\paragraph{Active Directory}
|
||||
|
||||
Active Directory is just an LDAP-server with predefined attributes. Sample
|
||||
config file is listed below:
|
||||
|
||||
\begin{verbatim}
|
||||
{auth_method, ldap}.
|
||||
{ldap_servers, ["office.org"]}. % List of LDAP servers
|
||||
{ldap_base, "DC=office,DC=org"}. % Search base of LDAP directory
|
||||
{ldap_rootdn, "CN=Administrator,CN=Users,DC=office,DC=org"}. % LDAP manager
|
||||
{ldap_password, "*******"}. % Password to LDAP manager
|
||||
{ldap_uidattr, "sAMAccountName"}.
|
||||
{ldap_filter, "(memberOf=*)"}.
|
||||
|
||||
{mod_vcard_ldap,
|
||||
[{ldap_vcard_map,
|
||||
[{"NICKNAME", "%u", []},
|
||||
{"GIVEN", "%s", ["givenName"]},
|
||||
{"MIDDLE", "%s", ["initials"]},
|
||||
{"FAMILY", "%s", ["sn"]},
|
||||
{"FN", "%s", ["displayName"]},
|
||||
{"EMAIL", "%s", ["mail"]},

{"ORGUNIT", "%s", ["department"]},
|
||||
{"CTRY", "%s", ["c"]},
|
||||
{"LOCALITY", "%s", ["l"]},
|
||||
{"STREET", "%s", ["streetAddress"]},
|
||||
{"REGION", "%s", ["st"]},
