During import, entries can be skipped if they do not belong in the specified backend, or if they are part of an excluded base DN or filter. The --skipFile {path} argument can be used on the command line to indicate that any entries that are skipped should be written to a specified file. You can add a comment indicating why the entries were skipped.

Similarly, the --rejectFile {path} argument can be added to obtain information about which entries were rejected and why. An entry can be rejected if it violates the server's schema constraints, if its parent entry does not exist, if another entry already exists with the same DN, or if it was rejected by a plugin.
