SYNOPSIS
LIBEXECDIR/slapd [-[4|6]] [-d debug-level] [-f slapd-con-
fig-file] [-h URLs] [-n service-name] [-s syslog-level]
[-l syslog-local-user] [-r directory] [-u user] [-g group]
[-t]
DESCRIPTION
Slapd is the stand-alone LDAP daemon. It listens for LDAP
connections on any number of ports (default 389), respond-
ing to the LDAP operations it receives over these connec-
tions. slapd is typically invoked at boot time, usually
out of /etc/rc.local. Upon startup, slapd normally forks
and disassociates itself from the invoking tty. If con-
figured in ETCDIR/slapd.conf, the slapd process will print
its process ID ( see getpid(2) ) to a .pid file, as well
as the command line options during invocation to an .args
file ( see slapd.conf(5) ). If the -d flag is given, even
with a zero argument, slapd will not fork and disassociate
from the invoking tty.
Slapd can be configured to provide replicated service for
a database with the help of slurpd, the standalone LDAP
update replication daemon. See slurpd(8) for details.
See the "OpenLDAP Administrator's Guide" for more details
on slapd.
OPTIONS-4 Listen on IPv4 addresses only.
-6 Listen on IPv6 addresses only.
-d debug-level
Turn on debugging as defined by debug-level. If
this option is specified, even with a zero argu-
ment, slapd will not fork or disassociate from the
invoking terminal. Some general operation and sta-
tus messages are printed for any value of
debug-level. debug-level is taken as a bit string,
with each bit corresponding to a different kind of
debugging information. See <ldap.h> for details.
Remember that if you turn on packet logging, pack-
ets containing bind passwords will be output, so if
you redirect the log to a logfile, that file should
be read-protected.
-s syslog-level
This option tells slapd at what level debugging
statements should be logged to the syslog(8) facil-
ity.
-n service-name
Specifies the service name for logging and other
purposes. Defaults to basename of argv[0], i.e.:
"slapd".
-l syslog-local-user
Selects the local user of the syslog(8) facility.
Values can be LOCAL0, LOCAL1, and so on, up to
LOCAL7. The default is LOCAL4. However, this
option is only permitted on systems that support
local users with the syslog(8) facility.
-f slapd-config-file
Specifies the slapd configuration file. The default
is ETCDIR/slapd.conf.
-h URLlist
slapd will by default serve ldap:/// (LDAP over TCP
on all interfaces on default LDAP port). That is,
it will bind using INADDR_ANY and port 389. The -h
option may be used to specify LDAP (and other
scheme) URLs to serve. For example, if slapd is
given -h "ldap://127.0.0.1:9009/ ldaps:///
ldapi:///" , It will bind 127.0.0.1:9009 for LDAP,
0.0.0.0:636 for LDAP over TLS, and LDAP over IPC
(Unix domain sockets). Host 0.0.0.0 represents
INADDR_ANY. A space separated list of URLs is
expected. The URLs should be of LDAP (ldap://) or
LDAP over TLS (ldaps://) or LDAP over IPC
(ldapi://) scheme without a DN or other optional
parameters, except an experimental extension to
indicate the permissions of the underlying socket,
on those OSes that honor them. Support for the
latter two schemes depends on selected configura-
tion options. Hosts may be specified by name or
IPv4 and IPv6 address formats. Ports, if specfied,
must be numeric. The default ldap:// port is 389
and the default ldaps:// port is 636. The socket
permissions for LDAP over IPC are indicated by "x-
mod=-rwxrwxrwx", "x-mod=0777" or "x-mod=777", where
any of the "rwx" can be "-" to suppress the related
permission (note, however, that sockets only honor
the "w" permission), while any of the "7" can be
any legal octal digit, according to chmod(1).
-r directory
Specifies a chroot "jail" directory. slapd will
chdir(2) then chroot(2) to this directory after
opening listeners but before reading any configura-
tion file or initializing any backend.
-u user
slapd will run slapd with the specified user name
or id, and that user's supplementary group access
list as set with initgroups(3). The group ID is
also changed to this user's gid, unless the -g
option is used to override.
-g group
slapd will run with the specified group name or id.
Note that on some systems, running as a non-privileged
user will prevent passwd back-ends from accessing the
encrypted passwords. Note also that any shell back-ends
will run as the specified non-privileged user.
-tslapd will read the configuration file (the default
if none is given with the -f switch) and check its
syntax, without opening any listener or database.
EXAMPLES
To start slapd and have it fork and detach from the termi-
nal and start serving the LDAP databases defined in the
default config file, just type:
LIBEXECDIR/slapd
To start slapd with an alternate configuration file, and
turn on voluminous debugging which will be printed on
standard error, type:
LIBEXECDIR/slapd -f /var/tmp/slapd.conf -d 255
To test whether the configuration file is correct or not,
type:
LIBEXECDIR/slapd -t
