NAME         top

       slapacl - Check access to a list of attributes.

SYNOPSIS         top

       SBINDIR/slapacl -b DN [-d debug-level] [-D authcDN | -U authcID]
       [-f slapd.conf] [-F confdir] [-o option[=value]] [-u] [-v]
       [-X authzID | -o  authzDN=DN] [attr[/access][:value]] [...]

DESCRIPTION         top

       slapacl is used to check the behavior of slapd(8) by verifying
       access to directory data according to the access control list
       directives defined in its configuration.  It opens the
       slapd.conf(5) configuration file or the slapd-config(5) backend,
       reads in the access/olcAccess directives, and then parses the
       attr list given on the command-line; if none is given, access to
       the entry pseudo-attribute is tested.

OPTIONS         top

       -b DN  specify the DN which access is requested to; the
              corresponding entry is fetched from the database, and thus
              it must exist.  The DN is also used to determine what
              rules apply; thus, it must be in the naming context of a
              configured database. By default, the first database that
              supports the requested operation is used.  See also -u.

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

       -D authcDN
              specify a DN to be used as identity through the test
              session when selecting appropriate <by> clauses in access

       -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.

       -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))

              Possible options/values specific to slapacl are:


              See the related fields in slapd.access(5) for details.

       -u     do not fetch the entry from the database.  In this case,
              if the entry does not exist, a fake entry with the DN
              given with the -b option is used, with no attributes.  As
              a consequence, those rules that depend on the contents of
              the target object will not behave as with the real object.
              The DN given with the -b option is still used to select
              what rules apply; thus, it must be in the naming context
              of a configured database.  See also -b.

       -U authcID
              specify an ID to be mapped to a DN as by means of
              authz-regexp or authz-rewrite rules (see slapd.conf(5) for
              details); mutually exclusive with -D.

       -v     enable verbose mode.

       -X authzID
              specify an authorization ID to be mapped to a DN as by
              means of authz-regexp or authz-rewrite rules (see
              slapd.conf(5) for details); mutually exclusive with -o

EXAMPLES         top

       The command

            SBINDIR/slapacl -f ETCDIR/slapd.conf -v \
                   -U bjorn -b "o=University of Michigan,c=US" \
                "o/read:University of Michigan"

       tests whether the user bjorn can access the attribute o of the
       entry o=University of Michigan,c=US at read level.
