ALL_FILTER

The ALL_FILTER keyword specifies a filter that is used by the dsexport command to regenerate the file from which the directory entries were originally created. This filter is necessary even if you do not intend to export information from the directory to regenerate the source file for that information.

The ALL_FILTER keyword is used by the directory server to retrieve from the directory all entries that belong to a given NIS table. This is because the directory server maintains a permanently up-to-date copy of the NIS tables.

The ALL_FILTER keyword is also used by the directory server to respond to commands such as ypcat.
