Application Interfaces
To configure the LDAP query you need to find out from the LDAP
server administrator what part of the subtree contains the desired
address information. The subtree is designated with a technical
address (DN, “Distinguished Name”). This technical address (in
the above example “ou=people,dc=mycompany,dc=com”) can be
defined in the web configurator on the Telephony: Extended:
Companies page with the BaseDN setting. If the LDAP server
does not allow an anonymous query, configure the settings User
name and Password for a LDAP user account with read authori-
sation.
Usage of address information queried via LDAP is activated as the
default setting for all user groups. You can deactivate this function
for individual user groups. To do so, deactivate the Use LDAP
option in the web configurator on the User Manager: User
groups page under the Phone book header.
After configuration, the information queried via LDAP is available
on authorised system telephone, DECT system terminals and SIP
system telephones as well as in the applications “ Forum 500 CTI”
and “Forum CTI Touch”. Information queried via LDAP is consid-
ered for telephone book searches and for displaying names during
incoming calls in addition to the information from the internal tel-
ephone book. Please note the following:
z When you have configured the LDAP query for a company, this
changes the telephone book search for the DECT system
terminals and corded system telephones. Instead of a
continuous display of search results, you have to first enter a
series of characters when entering for a search. Search results
can only be displayed after starting the search.
z Each individual LDAP-queried record is reserved for a definable
time in a Forum 523/524 communications system cache
(setting: Delete cache in minutes, 50 cache entries per
company each with a separate time counter per entry). You
should shorten this time (e. g. to 10 minutes) if, for example,
the assignment of guests and room telephones in a hotel is
managed via the LDAP server. If you set the Delete cache
setting to 0 minutes the cache is not automatically deleted.
Delete the cache as needed. Select the desired company
entries on the Telephony: Extended: Companies page and
click on the LDAP Delete cache button.
