.SH NAME
slapd.conf \- configuration file for slapd, the stand-alone LDAP daemon
.SH SYNOPSIS
ETCDIR/slapd.conf
.SH DESCRIPTION
The file
.B ETCDIR/slapd.conf
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
.BR slapadd (8),
.BR slapcat (8),
and
.BR slapindex (8).
.LP
The
.B slapd.conf
file consists of a series of global configuration options that apply to
.B slapd
as a whole (including all backends), followed by zero or more database
backend definitions that contain information specific to a backend
instance.
.LP
The general format of
.B slapd.conf
is as follows:
.LP
.nf
    # comment - these options apply to every database
    <global configuration options>
    # first database definition & configuration options
    database	<backend 1 type>
    <configuration options specific to backend 1>
    # subsequent database definitions & configuration options
    ...
.fi
.LP
As many backend-specific sections as desired may be included.  Global
options can be overridden in a backend (for options that appear more
than once, the last appearance in the
.B slapd.conf
file is used).  Blank lines and comment lines beginning with a `#'
character are ignored. If a line begins with white space, it is
considered a continuation of the previous line.
.LP
Arguments on configuration lines are separated by white space. If an
argument contains white space, the argument should be enclosed in
double quotes.  If an argument contains a double quote (`"') or a
backslash character (`\\'), the character should be preceded by a
backslash character.
.LP
The specific configuration options available are discussed below
in the Global Configuration Options, General Backend Options,
General Database Options, LDBM Database-Specific Options, Shell
Database-Specific Options, and Password Database-Specific Options
sections.  Refer to the "OpenLDAP Administrator's Guide" for more
details on the slapd configuration file.
.SH GLOBAL CONFIGURATION OPTIONS
Options described in this section apply to all backends, unless specifically 
overridden in a backend definition. Arguments that should be replaced by 
actual text are shown in brackets <>.
.TP
.B access to <what> [ by <who> <access> <control> ]+
Grant access (specified by <access>) to a set of entries and/or
attributes (specified by <what>) by one or more requestors (specified
by <who>).
See the "OpenLDAP's Administrator's Guide" for details.
.TP
.B allow <features>
Specify a set of features (separated by white space) to
allow (default none).
.B tls_2_anon

.RS
Specify an attribute type using the LDAPv3 syntax defined in RFC 2252.
The slapd parser extends the RFC 2252 definition by allowing string
forms as well as numeric OIDs to be used for the attribute OID and
attribute syntax OID.
(See the
.B objectidentifier
description.) Currently the syntax name parser is case-sensitive.

thread system as a hint.  The default is not to provide any hint.
.HP
.B defaultaccess { none | auth | compare | search | read | write }
.RS
Specify the default access level to grant requestors when
no access directives were provided for the database.
The default behavior is to grant 'read' access.  It is
recommended that
.B access
directives be used instead.

disables StartTLS if authenticated (see also
.B allow
.BR tls_2_anon ).
.TP
.B idletimeout <integer>
Specify the number of seconds to wait before forcibly closing
an idle client connections.  A idletimeout of 0 disables this
feature.  The default is 0.
.TP
.B include <filename>
Read additional configuration information from the given file before
continuing with the next line of the current file.
.TP
.B loglevel <integer>
Specify the level at which debugging statements and operation 
statistics should be syslogged (currently logged to the
.BR syslogd (8) 
LOG_LOCAL4 facility).  Log levels are additive, and available levels
are:

.B objectclass ( <oid> [NAME <name>] [DESC <description] [OBSOLETE]\
 [SUP <oids>] [{ ABSTRACT | STRUCTURAL | AUXILIARY }] [MUST <oids>]\
 [MAY <oids>] )
.RS
Specify an objectclass using the LDAPv3 syntax defined in RFC 2252.
The slapd parser extends the RFC 2252 definition by allowing string
forms as well as numeric OIDs to be used for the object class OID.
(See the
.B
objectidentifier
description.)  Object classes are "STRUCTURAL" by default.
.RE
.TP
.B objectidentifier <name> { <oid> | <name>[:<suffix>] }
Define a string name that equates to the given OID. The string can be used
in place of the numeric OID in objectclass and attribute definitions. The
name can also be used with a suffix of the form ":xx" in which case the
value "oid.xx" will be used.
.TP
.B password-hash <hash>
The <hash> to use for userPassword generation.  One of
.BR {SSHA} ,
.BR {SHA} ,
.BR {SMD5} ,
.BR {MD5} ,
and
.BR {CRYPT} .
The default is
.BR {SSHA} .
.TP
.B password-crypt-salt-format <format>
Specify the format of the salt passed to
.BR crypt (3)
when generating {CRYPT} passwords.  
This string needs to be in
.BR sprintf (3)
format and may include one (and only one) %s conversion.
This conversion will be substituted with a string random
characters from [A\-Za\-z0\-9./].  For example, "%.2s"
provides a two character salt and "$1$%.8s" tells some
versions of crypt(3) to use an MD5 algorithm and provides
8 random characters of salt.  The default is "%s", which
provides 31 characters of salt.
.TP
.B pidfile <filename>
The ( absolute ) name of a file that will hold the 
.B slapd
server's process ID ( see
.BR getpid (2)
) if started without the debugging command line option.
.TP
.B referral <url>
Specify the referral to pass back when
.BR slapd (8)
cannot find a local database to handle a request.
If specified multiple times, each url is provided.
.TP
.B require <conditions>
Specify a set of conditions (separated by white space) to
require (default none).
The directive may be specified globally and/or per-database.
.B bind
requires bind operation prior to directory operations.
.B LDAPv3
requires session to be using LDAP version 3.
.B authc
requires authentication prior to directory operations.
.B SASL
requires SASL authentication prior to directory operations.
.B strong
requires strong authentication prior to directory operations.
Currently
.B SASL
and
.B strong
conditions are currently same.
.B none
may be used to require no conditions (useful for clearly globally
set conditions within a particular database).
.TP
.B sasl-host <fqdn>
Used to specify the fully qualified domain name used for SASL processing.
.TP
.B sasl-realm <realm>
Specify SASL realm.  Default is empty.
.TP
.B sasl-secprops <properties>
Used to specify Cyrus SASL security properties.
The
.B none
flag (without any other properities) causes the flag properites
default, "noanonymous,noplain", to be cleared.
The
.B noplain
flag disables mechanisms susceptible to simple passive attacks.
The
.B noactive
flag disables mechanisms susceptible to active attacks.
The
.B nodict
flag disables mechanisms susceptible to passive dictionary attacks.
The
.B noanonyous
flag disables mechanisms which support anonymous login.
The
.B forwardsec
flag require forward secrecy between sessions.
The
.B passcred
require mechanisms which pass client credentials (and allow
mechanisms which can pass credentials to do so).
The
.B minssf=<factor> 
property specifies the minimum acceptable
.I security strength factor
as an integer approximate to effective key length used for
encryption.  0 (zero) implies no protection, 1 implies integrity
protection only, 56 allows DES or other weak ciphers, 112
allows triple DES and other strong ciphers, 128 allows RC4,
Blowfish and other modern strong ciphers.  The default is 0.
The
.B maxssf=<factor> 
property specifies the maximum acceptable
.I security strength factor
as an integer (see minssf description).  The default is INT_MAX.
The
.B maxbufsize=<size> 
property specifies the maximum security layer receive buffer
size allowed.  0 disables security layers.  The default is 65536.
.TP
.B schemacheck { on | off }
Turn schema checking on or off. The default is on.
.TP
.B security <factors>
Specify a set of factors (separated by white space) to require.
An integer value is associated with each factor and is roughly
equivalent of the encryption key length to require.  A value
of 112 is equivalent to 3DES, 128 to Blowfish, etc..
The directive may be specified globally and/or per-database.
.B ssf=<n>
specifies the overall security strength factor.
.B transport=<n>
specifies the transport security strength factor.
.B tls=<n>
specifies the TLS security strength factor.
.B sasl=<n>
specifies the SASL security strength factor.
.B update_ssf=<n>
specifies the overall security strength factor to require for
directory updates.
