ZARAFA-LDAP.CFG(5)

NAME
zarafa-ldap.cfg - The Zarafa LDAP configuration file

SYNOPSIS

ldap.cfg

DESCRIPTION

The ldap.cfg is a configuration file for LDAP user plugin. All options to correctly retrieve user and group information can be set here.

FILE FORMAT

The file consists of one big section, but parameters can be grouped by functionality.

The parameters are written in the form:

name = value

The file is line-based. Each newline-terminated line represents either a comment, nothing, a parameter or a directive. A line beginning with `#' is considered a comment, and will be ignored by Zarafa. Parameter names are case sensitive. Lines beginning with `!' are directives.

Directives are written in the form:

!directive [argument(s)]

The following directives exist:

include
    Include and process argument

    Example: !include common.cfg

propmap
    Propmap delivers the capabilities to map additional attributes to addressbook properties (e.g. firstname, lastname, telephonenumber).

    In the propmap the configuration names must be the hex property tag of the requested property. The value given to the configuration name must be the LDAP attribute to which the property should be mapped.

    Example: !propmap ldap.propmap.cfg

EXPLANATION OF EACH PARAMETER

ldap_host
    The hostname or ip-adress of the LDAP server.

    Default: localhost

ldap_port
    The port number of the LDAP server. LDAP normally runs on port 389.

    Default: 389

ldap_protocol
    The protocol to be used to connect to the LDAP server. Can be either 'ldap' or 'ldaps' for SSL connections. You will probably have to specify port 636 for ldap_port also. Zarafa will not use STARTTLS for such an SSL connection but instead will connect directly to an SSL encrypted port.

    Default: ldap

ldap_uri
    Instead of using ldap_host, ldap_port and ldap_protocol, you may also use ldap_uri which should specify the URI of the LDAP server like 'ldap://server:389'. If ldap_uri is set, the values of ldap_host, ldap_port and ldap_protocol are ignored. You may also specify multiple space-separated LDAP server URI's.

    Default:

ldap_server_charset
    The charset that the LDAP server uses to store strings. All strings sent to the LDAP server or retrieved from the server will be interpreted in this charset. In most setups, utf-8 is used, but may also be iso-8859-15. All charsets supported by the system iconv() are supported here.

    Default: utf-8

ldap_bind_user
    The bind dn as to connect to the LDAP server. Leave empty to connect anonymous.

    Default value is empty.

ldap_bind_passwd
    When ldap_bind_user is a valid DN, this should be filled in too.

    Default value is empty.

ldap_network_timeout
    The timeout for network operations in seconds.

    Default: 30

ldap_last_modification_attribute
    This value is used to detect changes in the item in the LDAP server. Since it is a standard LDAP attribute, you should never have to change this. It is mainly used for addressbook synchronisation between your server and your offline data.

    Default: modifyTimeStamp

ldap_page_size
    Limit result sets in pages of this size, downloading fewer results at a time from the LDAP server.

    Default: 1000

ldap_search_base
    This is the subtree entry where all objects are defined in the LDAP server.

    Default: dc=zarafa,dc=com

ldap_object_type_attribute
    An object is defined by this attribute what type it is, eg. user, group, etc. Every object type should have a unique value in this attribute in order to define what which enrty is.

    The value of this attribute must be specified in the ldap_*_type_attribute_value settings. Each of those settings may specify multiple values for the type attribute, separated by comma's. All of these values must be present in the objects type attribute for a match to be made and the object to be recognised as that type.

    It is possible for ambiguities to arise by setting the same string for multiple ldap_*_type_attribute_value settings. This ambiguity will be resolved by preferring objects with more matching values. If the ambiguity cannot be resolved in this way, then the first possibility is chosen from the list (addresslist, tenant, dynamic group, group, contact, user).

    Default: objectClass

ldap_user_type_attribute_value
    The value in ldap_object_type_attribute which defines a user.

    Default for OpenLDAP: posixAccount

ldap_addressbook_hide_attribute
    The attribute indicating the object must be hidden from the addressbook. The object will still be detected as zarafa user and is allowed to login and work as regular zarafa user, but will not be visible in the addressbook for other users.

    Default: zarafaHidden

ldap_object_search_filter
    When searching in the addressbook, this filter will be used. Normally, the zarafa server will only search in the unique attribute, loginname, fullname and emailaddress. You might want to search in more fields, like 'lastname'. Zarafa also uses a postfix wildcard only. Using the '*' wildcard with prefixes makes a search slower, but can return more results.

    Hint: Use the zarafaAccount attribute in the filter to differentiate between non-zarafa and zarafa objects.

    You can set a custom search filter here. '%s' will be replaced with the string being searched.

    Active Directory has a shortcut for searching in the addressbook using the 'anr' attribute. This is recommended on ADS installations.

    Default:

    Recommended for ADS installations: (anr=%s)

    Optional for OpenLDAP installations: (|(mail=%s*)(uid=%s*)(cn=*%s*)(fullname=*%s*)(givenname=*%s*)(lastname=*%s*)(sn=*%s*))

ldap_filter_cutoff_elements
    When the ldap plugin retrieves information from the LDAP Server, large queries can be created to retrieve data for multiple objects at once. These large queries can perform badly on some LDAP server implementations. This option limits the number of elements that can be retrieved in one search filter and therefore limits the size of the filter. Instead, a broader search filter is created which retrieves all objects from the LDAP server. This results in slightly higher processing overhead and network activity, but with the bonus that the query can be served by the LDAP server much faster (a factor of 40 in 5000-object queries has been observed).

    Setting this value to 0 will never limit the filter, setting it to a value of 1 will always limit the filter (since all queries will be retrieving one or more objects).

    Default: 1000
