Vorkonfigurieren der Pakete ... Konfiguriere slapd ------------------ Before upgrading to a new version of the OpenLDAP server the data of your LDAP directories can be dumped to plain text files (LDIF format) which is a standardized description of that data (LDIF stands for LDAP Data Interchange Format). Selecting "always" will make the maintainer scripts dump your databases before upgrading unconditionally. Selecting "when needed" will only dump the database if the new version is incompatible with the old database format and it has to be reimported. The "never" choice will just go ahead without ever dumping your database. 1. always 2. when needed 3. never (...1, accept the default...) Please specify the directory where the LDAP databases will be exported. Within this directory several LDIF files are created which correspond to the search bases located on the server. Make sure you have enough free space on the partition the directory is located. The first occurrence of the string "VERSION" is replaced with the server version you are upgrading from. The default is /var/backups/slapd-VERSION ... Vorbereiten zum Ersetzen von ldap-utils 2.1.23-1 (durch .../ldap-utils_2.2.23-8_i386.deb) ... Entpacke Ersatz für ldap-utils ...
