File README.update of Package openldap2
Updating from OpenLDAP 2.3.X to 2.4.X
Changed Database format:
Due change in the "BDB"-backend's index database format, existing
bdb-databases need to be reloaded from LDIF completely. This is
normally done during the package installation/update. This might not
work in all setups and for that database dumps of all bdb/hdb
databases are created during the update.
You can find the database dump of each bdb database in the
database directory for that database (default: /var/lib/ldap/). The
file name is "ldapbak.ldif.X" where "X" presents the number of the
If the database backups where not created during the package update for
some reason, you can do them manually by using the command:
/usr/sbin/openldap-2.3-slapcat -T c \
Before dumping the database you should remove the db's enviroment (the
__db*-file in /var/lib/ldap)
To reload the databases please use the tool "slapadd".
For additional information on important changes and upgrade
instructions, please have a look a the OpenLDAP Administrator's Guide.
