LDAP Address Book
LDAP stands for Lightweight Directory Access Protocol and is directory of contacts. The ldap server ldap.aegee.org (standard port 389, does require STARTTLS) offers the contact data of all bodies. The same data is available over CardDAV and in https://my.aegee.eu/bodies. It can be setup as address book in different applications.
Go to File → New → Address Book . Type: “On LDAP Servers”.
In the tab “Connecting to LDAP” enter as Server: ldap.aegee.org , Leave port: 389, Encryption: STARTTLS, Authentication Method: Anonymous, Username: empty.
In the tab “Using LDAP” enter as Search base “o=AEGEE". (The button ”Find Possible Search Bases“ does not work), Search scope: Subtree.
