commit e8d800073566a854e06bedd71d9ae48d9e893453 Author: Ludwig Krispenz lkrispen@redhat.com AuthorDate: Thu Dec 19 14:33:52 2019 +0100
Ticket: 50755 - setting nsslapd-db-home-directory is overriding db_directory
Bug: If nsslapd-db-home-directory is set for new instances the database is placed below this directory, not only the db environment.
Fix: Use the db dir when looking up the instance dir. Make sure the log dir is below db dir and not home dir. Make sure dse.ldif is written if upgrade to split config is done in a non-normal mode, eg import Make sure the db directory is set to the list of parent directories for instances If dblayer is closed only temporarily do not free directory settings Adjust log level of some error messages
