What are the corporate directory (LDAP) settings?
Below is a list of all the corporate directory settings and their descriptions.
|Name||The name used to identify the directory in the admin portal.|
|Host||Host DNS name or IP address of the directory server. Devices must be able to resolve this address since the searches are executed directly from the phone to the directory server.|
|Port||The default LDAP port is 389. It is unusual for this value to be different. LDAPS is not always supported. As a result, make sure to use a username with read-only access. If LDAPS is deployed, the correct port will need to be entered (usually 636).|
|Use TLS||Enable this setting to use LDAP over TLS. This is only supported on Polycom devices and where the LDAP server has a valid certificate.|
|Bind DN||The distinguished name (DN) with which devices will bind (authenticate).|
|Bind Password||Password required for the phone to authenticate as the given Bind DN.
Note: LDAPS is only supported on Polycom phones and only if an appropriate certificate (see the Certificate tab below) is uploaded. Unless an appropriate certificate has been uploaded, the bind password will be sent in clear text across the network. If you do not have a valid certificate, it is highly recommended that the bind DN should be a read-only user. Certificates are only usable on Polycom devices. On all other manufacturers handsets, the bind password will ALWAYS be sent in clear text. Failure to use credentials with read-only access can lead to the directory service being compromised.
|Search Base||Directory location where searches will be based. We recommend using a narrow search base. The impact of the searches can be minimized by using a more specific search base. (e.g., "ou=Users,dc=example,dc=com" is better than "dc=example,dc=com").|
|Search Scope||Depth of the search through the directory tree.
|Filter — Optional||Filter added to all searches made by the devices against the directory server. We recommend using a narrow filter. Defining a filter like “(objectclass=person)” can significantly reduce search load in certain directory implementations.|
|Display Name Attribute||Attribute used as the name in results returned to the device in searches. Used for Cisco/Linksys SPA devices. For Polycom SoundPoint IP devices, the results are displayed [Last Name Attribute], [First Name Attribute].|
|First Name Attribute||Attribute that contains the first name in the directory. Devices will also filter against this attribute in searches.|
|Last Name Attribute||Attribute that contains the last name in the directory. Devices will also filter against this attribute in searches.|
|Phone Number Attributes||A comma separated list of phone number attributes in the directory. In the case of Cisco/Linksys SPA devices, the first listed phone number is the only number that the device can directly dial. The rest are only displayed for informational purposes.|
Only Polycom devices support the use of certificates to enable LDAP using TLS.
