Dynamic Section

The Dynamic section contains equations that make it possible to dynamically build the filters required to locate relevant information.

LINE

The LINE keyword is necessary to define how the input information must be dynamically decomposed to provide the elements required in the MATCH_FILTER and ALL_FILTER definitions.

The syntax of the LINE keyword is given in "Extract".

MATCH_FILTER

The MATCH_FILTER keyword specifies a filter that is used by the dsimport utility to check whether an entry already exists in the database before creating it. If it exists, the dsimport utility will check whether it needs to be modified.

The MATCH_FILTER keyword is also used by the directory server to respond to commands such as ypmatch.

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.

DC_NAMING

The DC_NAMING keyword defines the mechanism applied to convert a domain name of the form xyz.com to an LDAP data store suffix or naming context of the form dc=xyz, dc=com. This is useful if the naming structure that you use in your directory is a domain component (dc) structure.
