SLAPSCHEMA(8C)                                                                                SLAPSCHEMA(8C)



NAME
       slapschema - SLAPD in-database schema checking utility

SYNOPSIS
       /usr/sbin/slapschema  [-afilter]  [-bsuffix]  [-c]  [-ddebug-level]  [-fslapd.conf]  [-Fconfdir] [-g]
       [-HURI] [-lerror-file] [-ndbnum] [-ooption[=value]] [-ssubtree-dn] [-v]


DESCRIPTION
       Slapschema is used to check schema compliance of the contents of a slapd(8) database.  It  opens  the
       given  database determined by the database number or suffix and checks the compliance of its contents
       with the corresponding schema. Errors are written to standard output or the  specified  file.   Data-bases Databases
       bases configured as subordinate of this one are also output, unless -g is specified.

       Administrators  may need to modify existing schema items, including adding new required attributes to
       objectClasses, removing existing required or allowed attributes from objectClasses, entirely removing
       objectClasses,  or  any other change that may result in making perfectly valid entries no longer com-pliant compliant
       pliant with the modified schema.  The execution of the slapschema tool after modifying the schema can
       point out inconsistencies that would otherwise surface only when inconsistent entries need to be mod-ified. modified.
       ified.


       The entry records are checked in database order, not superior first order.  The entry records will be
       checked considering all (user and operational) attributes stored in the database.  Dynamically gener-ated generated
       ated attributes (such as subschemaSubentry) will not be considered.

OPTIONS
       -a filter
              Only check entries matching the asserted filter.  For example

              slapschema -a \
                  "(!(entryDN:dnSubtreeMatch:=ou=People,dc=example,dc=com))"

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

       -b suffix
              Use  the specified suffix to determine which database to check.  The -b cannot be used in con-junction conjunction
              junction 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  try-ing trying
              ing 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 entries.

       -l error-file
              Write errors to specified file instead of standard output.

       -n dbnum
              Check  the  dbnum-th database listed in the configuration file. The config database slapd-con-fig(5), slapd-config(5),
              fig(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 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))


       -s subtree-dn
              Only check entries in the subtree specified by this DN.  Implies -b subtree-dn if no -b nor -n
              option is given.  Deprecated; use -H ldap:///subtree-dn instead.

       -v     Enable verbose mode.

LIMITATIONS
       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  slapschema  with  the
       slapd-bdb(5), slapd-hdb(5), and slapd-null(5) backends.

EXAMPLES
       To  check the schema compliance of your SLAPD database after modifications to the schema, and put any
       error in a file called errors.ldif, give the command:

            /usr/sbin/slapcat -l errors.ldif
