The LDAP directory server must offer an LDAP V2 or V3 interface and provide access using password-based, so-called "simple" security.

The contact data is stored on the LDAP directory server using the keys that were configured on the OpenScape 4000 SoftGate via WBM.

It is recommended that the telephone numbers are stored in a fully qualified format including country code and area code (e.g. 4989700754321). If the numbers are stored using separators such as brackets, dashes or plus signs (e.g. +49 (89) 7007-54321), then the LDAP directory server has to apply conversion rules when checking for a match. The OpenStage phone issues an LDAP query using plain digits without separators.

Example of an LDAP structure:

The entries in the attribute type column marked red must be provided to the OpenScape 4000 SoftGate via the WBM configuration (see OpenScape 4000 SoftGate configuration).

The screenshot below looks at the nodes where the telephone contact data is found.

The base node for searching is selected with o=scd.

Another example using a different LDAP directory server in direct mode:

As can be seen, the node structure in this server is very simple. The base node is selected with ou=system.
