SLAPINDEX(8) System Manager's Manual SLAPINDEX(8)
NAME
slapindex - Reindex entries in a SLAPD database
SYNOPSIS
/usr/sbin/slapindex [-b suffix] [-c] [-d debug-level] [-f slapd.conf]
[-F confdir] [-g] [-n dbnum] [-o option[=value]] [-q] [-t] [-v]
[attr[...]]
DESCRIPTION
Slapindex is used to regenerate slapd(8) indices based upon the current
contents of a database. It opens the given database determined by the
database number or suffix and updates the indices for all values of all
attributes of all entries. If a list of specific attributes is provided
on the command line, only the indices for those attributes will be re-
generated. Databases configured as subordinate of this one are also re-
indexed, unless -g is specified.
All files eventually created by slapindex will belong to the identity
slapindex is run as, so make sure you either run slapindex with the same
identity slapd(8) will be run as (see option -u in slapd(8)), or change
file ownership before running slapd(8).
OPTIONS
-b suffix
Use the specified suffix to determine which database to generate
output for. By default, the first database that supports the re-
quested operation is used. The -b cannot be used in conjunction
with the -n option.
-c enable continue (ignore errors) mode.
-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).
-n dbnum
Generate output for the dbnum-th database listed in the configu-
ration file. The config database slapd-config(5), is always the
first database, so use -n 0
The -n cannot be used in conjunction with the -b option.
-o option[=value]
Specify an option with a(n optional) value. Possible generic op-
tions/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))
-q enable quick (fewer integrity checks) mode. Performs no consis-
tency checks when writing the database. Improves indexing time,
however the database will most likely be unusable if any errors
or interruptions occur.
-t enable truncate mode. Truncates (empties) an index database be-
fore indexing any entries. May only be used with back-mdb.
-v enable verbose mode.
LIMITATIONS
Your slapd(8) should not be running (at least, not in read-write mode)
when you do this to ensure consistency of the database.
slapindex ought to be run as the user specified for slapd(8) to ensure
correct database permissions.
This command provides ample opportunity for the user to obtain and drink
their favorite beverage.
EXAMPLES
To reindex your SLAPD database, give the command:
/usr/sbin/slapindex
To regenerate the index for only a specific attribute, e.g. "uid", give
the command:
/usr/sbin/slapindex uid
