➢
To enable and configure the LDAP cache:
1. Open the LDAP Settings page (Setup menu > IP Network tab > RADIUS & LDAP folder >
LDAP Settings).
2. From the 'LDAP Cache Service' drop-down list, select Enable to enable LDAP cache.
3. In the 'LDAP Cache Entry Timeout' field, enter the duration (in minutes) for which an entry in
the LDAP cache is valid.
4. In the 'LDAP Cache Entry Removal Timeout' field, enter the duration (in hours) after which the
device removes the LDAP entry from the cache.
5. Click Apply, and then reset the device with a save-to-flash for your settings to take effect.

Refreshing the LDAP Cache

You can refresh values of LDAP Attributes associated with a specified LDAP search key that are
stored in the device's LDAP cache. The device sends an LDAP query to the LDAP server for the
cached Attributes of the specified search key and replaces the old values in the cache with the new
values received in the LDAP response.
For example,
"telephoneNumber=1004" whose associated Attributes include "displayName", "mobile" and
"ipPhone". If you perform a cache refresh based on the search key "telephoneNumber=1004", the
device sends an LDAP query to the server requesting values for the "displayName", "mobile" and
"ipPhone" Attributes of this search key. When the device receives the LDAP response, it replaces
the old values in the cache with the new values received in the LDAP response.
The LDAP Cache feature is applicable only to LDAP-based SIP queries (Control).
The maximum LDAP cache size is 10,000 entries.
The device can save up to six LDAP Attributes in the cache per searched LDAP
key.
The device also saves in the cache queried Attributes that do not have any values
in the LDAP server.
