LDAP Server
Proceed as follows:
Using the Configuration Manager (page User data > Address books > Settings)
Enable server
The PBX's LDAP server is one of the databases based on this protocol. It stores the contact data for the PBX's central address books. As the LDAP server displays the contact data stored in the central address books, it can also hold up to 2000 contacts like the address books.
The LDAP server is needed to transfer the PBX's contact data to those IP end devices which support this transfer method (e.g. IP DECT servers or SIP phones with LDAP support). Any contact data that is input directly on a phone is not transferred to the central address books.
Auerswald/FONtevo provides LDAP support for the following IP end devices:
IP phone: COMfortel 1200 IP
IP phones: COMfortel 1400 IP/2600 IP/3600 IP (firmware version 2.4A, or later)
IP-DECT server: COMfortel WS-400 IP, COMfortel WS-650 IP (only Auerswald)
IP-DECT handsets: COMfortel M-100/200/210/300/310 (only Auerswald)
Contact data can be transferred to the IP end devices.
* Note: When switched off, the security and performance of the PBX are improved. No contact data can be transferred to the IP end devices.
* Note: The LDAP server's IP address matches the PBX's IP address and is predefined.
Simplified user name
Freely selectable part of the user name.
The user name along with the associated password is needed for authentification of IP end devices on the LDAP server so that they have (only read) access to all the contact data that is currently present on the LDAP server.
Exported contact groups
Requirements:
At least one contact group that is configured in the address books
Select the contact groups (up to 5), which are transferred to the LDAP server and therefore also to the IP end devices.
The user name resulting from the name of the contact group along with the associated password is needed for authentification of IP end devices on the LDAP server so that they have (only read) access to the contact data for this contact group.
Password
Freely selectable password that consists of 8 to 32 characters containing digits, letters (upper and lower case, but no German umlauts and ß) and special characters - _ . ! ~ * ' ( ) & = + $ ,.
* Note: To change current passwords, click on  Edit passwords.
* Note: A coloured bar under the entry field shows the security level of the password (red = low level, green = high level).
* Note: Passwords with a low security level can not be saved.
* Caution: A high level does not necessarily indicate a secure password as this can also be reached by entering names and birth dates in connection with special characters. However, names and birth dates should not be used as passwords.
To create a secure password you can consult, for example, the guidelines of the German Federal Office for Information Security (BSI, in German).
* Caution: Visible passwords are a security risk.
After entering the PIN/password, click on  Hide passwords.
