slapacl(8)
NAME
slapacl - Check access to a list of attributes.
SYNOPSIS
/usr/sbin/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
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
-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. 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 lists.
-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:
authzDN
domain
peername
sasl_ssf
sockname
sockurl
ssf
tls_ssf
transport_ssf
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 authzDN=DN.
EXAMPLES
The command
/usr/sbin/slapacl -f /etc/ldap/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.
