SLAPCAT(8C)                                                      SLAPCAT(8C)

NAME         top

       slapcat - SLAPD database to LDIF utility

SYNOPSIS         top

       SBINDIR/slapcat [-afilter] [-bsuffix] [-c] [-ddebug-level]
       [-fslapd.conf] [-Fconfdir] [-g] [-HURI] [-lldif-file] [-ndbnum]
       [-ooption[=value]] [-ssubtree-dn] [-v]

DESCRIPTION         top

       Slapcat is used to generate an LDAP Directory Interchange Format
       (LDIF) output based upon the contents of a slapd(8) database.  It
       opens the given database determined by the database number or suffix
       and writes the corresponding LDIF to standard output or the specified
       file.  Databases configured as subordinate of this one are also
       output, unless -g is specified.

       The entry records are presented in database order, not superior first
       order.  The entry records will include all (user and operational)
       attributes stored in the database.  The entry records will not
       include dynamically generated attributes (such as subschemaSubentry).

       The output of slapcat is intended to be used as input to slapadd(8).
       The output of slapcat cannot generally be used as input to ldapadd(1)
       or other LDAP clients without first editing the output.  This editing
       would normally include reordering the records into superior first
       order and removing no-user-modification operational attributes.

OPTIONS         top

       -a filter
              Only dump entries matching the asserted filter.  For example

              slapcat -a \

              will dump all but the "ou=People,dc=example,dc=com" subtree of
              the "dc=example,dc=com" database.  Deprecated; use -H
              ldap:///???(filter) instead.

       -b suffix
              Use the specified suffix to determine which database to
              generate output for.  The -b cannot be used in conjunction
              with the -n option.

       -c     Enable continue (ignore errors) mode.  Multiple occurrences of
              -c make slapcat(8) try harder.

       -d debug-level
              Enable debugging messages as defined by the specified debug-
              level; see slapd(8) for details.

       -f slapd.conf
              Specify an alternative slapd.conf(5) file.

       -F confdir
              specify a config directory.  If both -f and -F are specified,
              the config file will be read and converted to config directory
              format and written to the specified directory.  If neither
              option is specified, an attempt to read the default config
              directory will be made before trying to use the default config
              file. If a valid config directory exists then the default
              config file is ignored.

       -g     disable subordinate gluing.  Only the specified database will
              be processed, and not its glued subordinates (if any).

       -H  URI
              use dn, scope and filter from URI to only handle matching

       -l ldif-file
              Write LDIF to specified file instead of standard output.

       -n dbnum
              Generate output for the dbnum-th database listed in the
              configuration file. The config database slapd-config(5), is
              always the first database, so use -n 0 to select it.

              The -n cannot be used in conjunction with the -b option.

       -o option[=value]
              Specify an option with a(n optional) value.  Possible generic
              options/values are:

                     syslog=<subsystems>  (see `-s' in slapd(8))
                     syslog-level=<level> (see `-S' in slapd(8))
                     syslog-user=<user>   (see `-l' in slapd(8))


              n is the number of columns allowed for the LDIF output
              (n equal to 0 uses the default, corresponding to 78).
              The minimum is 2, leaving space for one character and one
              continuation character.
              Use no for no wrap.

       -s subtree-dn
              Only dump entries in the subtree specified by this DN.
              Implies -b subtree-dn if no
              option is given.
              Deprecated; use -H ldap:///subtree-dn instead.

       -v     Enable verbose mode.

LIMITATIONS         top

       For some backend types, your slapd(8) should not be running (at
       least, not in read-write mode) when you do this to ensure consistency
       of the database. It is always safe to run slapcat with the
       slapd-mdb(5), and slapd-null(5) backends.

EXAMPLES         top

       To make a text backup of your SLAPD database and put it in a file
       called ldif, give the command:

            SBINDIR/slapcat -l ldif
