LDAP

The Lightweight Directory Access Protocol (LDAP), is an application protocol that programs use for querying

information from a server. The protocol runs over TCP/IP. Deployments today tend to use Domain Name System

(DNS) names for structuring the topmost levels of the hierarchy. LDAP servers index all the data in their entries,

and "filters" can be used to select the person or group for which you are looking. LDAP is appropriate for any

kind of directory-like information, where fast lookups and less-frequent updates are the norm. For example,

when you use Microsoft

Outlook and search the address book for a colleague, you access the Microsoft

Active

Directory database via LDAP.

How to Use LDAP to Access Active Directory for Routing Calls via Diva SIPcontrol

You can enable LDAP functionality via Diva SIPcontrol web configuration. When LDAP is activated, Diva SIPcontrol

will query the server on startup and store the query results internally for a faster lookup. In a default configuration,

this internal storage will be updated once a day to reflect changes on the LDAP database. If you use LDAP, you

need to configure two routes for one LDAP call:

• One route should contain the LDAP destination.

• The other route should contain the final destination.

The order of the routes is irrelevant, but it is important to configure the first route with the conditions needed

to avoid recursion.

Authentication mode: Select how the server-client authentication should be handled:

• Mutual Authentication: MTLS is used by Microsoft

Office Communications

Server 2007 Server roles and by Microsoft

Exchange 2007 UM role to

communicate with each other. In this mode, both peers need to authenticate

each other and both client and server exchange certificates.

For connecting to Lync Server or Microsoft

Office Communications Server

2007 R2 Mediation Server via TLS, use Standard TLS authentication mode. For

a direct connection to Microsoft

Exchange 2007 UM role via TLS, use MTLS

authentication mode.

• Standard TLS Authentication: This is the normal authentication mode, in

which the client asks the server for authentication to ensure a secure

connection to the correct server.

• No Authentication: In this mode, neither the server nor the client needs to

prove its authentication.

The default setting is Standard TLS Authentication.

Certificate date

verification:

If enabled, the expiration date of the peer certificate is verified. If the certificate

is expired, an informational message is displayed and the call is aborted.
