SLAPD-LDIF(5)							File Formats Manual						     SLAPD-LDIF(5)

NAME

       slapd-ldif - LDIF backend to slapd

SYNOPSIS

       /etc/openldap/slapd.conf

DESCRIPTION

       The  LDIF  backend  to slapd(8) is a basic storage backend that stores entries in text files in LDIF format, and exploits the filesystem to
       create the tree structure of the database.  It is intended as a cheap, low performance easy to use backend, and it is exploited by  higher-
       level internal structures to provide a permanent storage.

CONFIGURATION

       These  slapd.conf  options apply to the LDIF backend database.  That is, they must follow a "database ldif" line and come before any subse-
       quent "backend" or "database" lines.  Other database options are described in the slapd.conf(5) manual page.

       directory <dir>
	      Specify the directory where the database tree starts.  The directory must exist and grant appropriate permissions (rwx) to the iden-
	      tity slapd is running with.

ACCESS CONTROL

       The  LDIF  backend  does  not  honor  any of the access control semantics described in slapd.access(5).	Only read (=r) access to the entry
       pseudo-attribute and to the other attribute values of the entries returned by the search operation is honored, which is	performed  by  the
       frontend.

FILES

       /etc/openldap/slapd.conf
	      default slapd configuration file

SEE ALSO

       slapd.conf(5), slapd-config(5), slapd(8), ldif(5).
