Before you start

The EBCA directory service can easily be integrated in the user’s email client. The following date is relevant for this step:

Server of the directory service
Port                                                  389
Search basis                                   o=ebca

Step-by-step guide for retrieving a certificate using the web interface



1. Open Outlook and go to "account information". There, go to "file" (1) – "info" (2) – "account settings" (3) – "account settings" (4).
2. A new window will open. Now go to "address books" and click the "new" button.
3. Select "internet directory service (LDAP)" and click "next".
4. Fill in "" as the new server name and click "more settings".
5. Add port "389" under "connections" and fill in "o=ebca" under "search".

Please define an order of retrieval for an automatic request when sending enciphered messages. This can be done as follows:

1. Go to "Start" and select the "address book" button.
2. Go to "tools" and select "options".
3. Add a new address list.
4. Select the new address list and click "add" and then "close".
5. Move the new entry to the top position with the help of the arrow button. Now, the EBCA directory service will automatically retrieve certificate if the user wants to send an enciphered message.

The service provider of your standard email client will demonstrate how to install and integrate LDAP directory services in your email client.
