.SH NAME
slapd.access \- access configuration for slapd, the stand-alone LDAP daemon
.SH SYNOPSIS
.BR slapd.conf (5)
file contains configuration information for the
.BR slapd (8)
-daemon. This configuration file is also used by the
-.BR slurpd (8)
-replication daemon and by the SLAPD tools
+daemon. This configuration file is also used by the SLAPD tools
.BR slapacl (8),
.BR slapadd (8),
.BR slapauth (8),
not applicable, the directives from the global configuration section
are then used.
.LP
+If no access controls are present, the default policy
+allows anyone and everyone to read anything but restricts
+updates to rootdn. (e.g., "access to * by * read").
+.LP
+When dealing with an access list, because the global access list is
+effectively appended to each per-database list, if the resulting
+list is non-empty then the access list will end with an implicit
+.B access to * by * none
+directive. If there are no access directives applicable to a backend,
+then a default read is used.
+.LP
+.B Be warned: the rootdn can always read and write EVERYTHING!
+.LP
For entries not held in any backend (such as a root DSE), the
-directives of the first backend (and any global directives) are
-used.
+global directives are used.
.LP
Arguments that should be replaced by actual text are shown in
brackets <>.
.SH THE ACCESS DIRECTIVE
The structure of the access control directives is
.TP
-.B access to <what> "[ by <who> <access> [ <control> ] ]+"
+.B access to <what> "[ by <who> [ <access> ] [ <control> ] ]+"
Grant access (specified by
.BR <access> )
to a set of entries and/or attributes (specified by
.BR <what> )
by one or more requestors (specified by
.BR <who> ).
+
+.LP
+Lists of access directives are evaluated in the order they appear
+in \fIslapd.conf\fP.
+When a
+.B <what>
+clause matches the datum whose access is being evaluated, its
+.B <who>
+clause list is checked.
+When a
+.B <who>
+clause matches the accessor's properties, its
+.B <access>
+and
+.B <control>
+clauses are evaluated.
+Access control checking stops at the first match of the
+.B <what>
+and
+.B <who>
+clause, unless otherwise dictated by the
+.B <control>
+clause.
+Each
+.B <who>
+clause list is implicitly terminated by a
+.LP
+.nf
+ by * none stop
+.fi
+.LP
+clause that results in stopping the access control with no access
+privileges granted.
+Each
+.B <what>
+clause list is implicitly terminated by a
+.LP
+.nf
+ access to *
+ by * none
+.fi
+.LP
+clause that results in granting no access privileges to an otherwise
+unspecified datum.

refers to everybody.
.LP
+The keywords prefixed by
+.B real
+act as their counterparts without prefix; the checking respectively occurs
+with the \fIauthentication\fP DN and the \fIauthorization\fP DN.
+.LP
The keyword
.B anonymous
means access is granted to unauthenticated clients; it is mostly used
.B self
means access to an entry is allowed to the entry itself (e.g. the entry
being accessed and the requesting entry must be the same).
+It allows the
+.B level{<n>}
+style, where \fI<n>\fP indicates what ancestor of the DN
+is to be used in matches.
+A positive value indicates that the <n>-th ancestor of the user's DN
+is to be considered; a negative value indicates that the <n>-th ancestor
+of the target is to be considered.
+For example, a "\fIby self.level{1} ...\fP" clause would match
+when the object "\fIdc=example,dc=com\fP" is accessed
+by "\fIcn=User,dc=example,dc=com\fP".
+A "\fIby self.level{-1} ...\fP" clause would match when the same user

Since the dollar character is used to indicate a substring replacement,

.LP
The style qualifier
.B dnstyle
is not
.BR regex .
+Note that the
+.B regex
+dnstyle in the above example may be of use only if the
+.B <by>
+clause needs to be a regex; otherwise, if the
+value of the second (from the right)
+.B dc=
+portion of the DN in the above example were fixed, the form
+.LP
+.nf
+ access to dn.regex="^(.+,)?uid=([^,]+),dc=example,dc=com$"
+ by dn.exact,expand="uid=$2,dc=example,dc=com" write
+.fi
+.LP
+could be used; if it had to match the value in the

+clause, the form

+ access to dn.regex="^(.+,)?uid=([^,]+),dc=([^,]+),dc=com$"
+ by dn.exact,expand="uid=$2,dc=$3,dc=com" write
+.fi
+.LP
+could be used.
+.LP
+Forms of the
+.B <what>
+clause other than regex may provide submatches as well.
+The
+.BR base(object) ,
+the
+.BR sub(tree) ,
+the
+.BR one(level) ,
+and the
+.BR children
+forms provide
+.B $0
+as the match of the entire string.
+The
+.BR sub(tree) ,
+the
+.BR one(level) ,
+and the
+.BR children
+forms also provide
+.B $1
+as the match of the rightmost part of the DN as defined in the
+.B <what>
+clause.
+This may be useful, for instance, to provide access to all the
+ancestors of a user by defining
+.LP
+.nf
+ access to dn.subtree="dc=com"
+ by dn.subtree,expand="$1" read
+.fi
+.LP
+which means that only access to entries that appear in the DN of the
+.B <by>
+clause is allowed.
+.LP
+The
+.BR level{<n>}
+form is an extension and a generalization of the
+.BR onelevel
+form, which matches all DNs whose <n>-th ancestor is the pattern.
+So, \fIlevel{1}\fP is equivalent to \fIonelevel\fP,
+and \fIlevel{0}\fP is equivalent to \fIbase\fP.
.LP
It is perfectly useless to give any access privileges to a DN
that exactly matches the

+and
.BR exact ,
which means that exact match will be used.
+If the style of the DN portion of the
+.B <what>
+clause is regex, the submatches are made available according to
+.BR regex (7)
+and/or
+.BR re_format (7);
+other styles provide limited submatches as discussed above about
+the DN form of the

.LP
For static groups, the specified attributeType must have

+The same applies to IPv6 addresses when the special

+The statement
+.B dynacl/aci[=<attrname>]
means that the access control is determined by the values in the

of the entry itself.
