DESCRIPTION
Slapd is the stand-alone LDAP daemon. It listens for LDAP connections
on any number of ports (default 389), responding to the LDAP operations
it receives over these connections. 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 configured in
/opt/local/etc/openldap/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.
-T (a|c|i|p)
Run in Tool mode. The additional argument selects whether to run
as slapadd, slapcat, slapindex, or slappasswd. This option
should be the first option specified when it is used. Any
remaining options will be interpreted by the corresponding slap
tool program. Note that these tool programs will usually be sym-
bolic links to slapd. This option is provided for situations
where symbolic links are not provided or not usable.
-d debug-level
Turn on debugging as defined by debug-level. If this option is
specified, even with a zero argument, slapd will not fork or
disassociate from the invoking terminal. Some general operation
and status messages are printed for any value of debug-level.
debug-level is taken as a bit string, with each bit correspond-
ing 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) facility.
-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 the LDAP, LDAPS, or LDAPI schemes, and gener-
ally without a DN or other optional parameters (excepting as
discussed below). Support for the latter two schemes depends on
selected configuration options. Hosts may be specified by name
or IPv4 and IPv6 address formats. Ports, if specified, 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). While LDAP over IPC requires
write permissions on the socket to allow any operation, the
other listeners can take advantage of the "x-mod" extension to
apply rough limitations to users, e.g. allow read operations
("r", which applies to search and compare), write operations
("w", which applies to add, delete, modify and modrdn), and exe-
cute operations ("x", which means bind is required). "User"
permissions apply to bound users, while "other" apply to anony-
mous users.
-r directory
Specifies a chroot "jail" directory. slapd will chdir(2) then
chroot(2) to this directory after opening listeners but before
reading any configuration 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 init-
groups(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 pre-
vent passwd back-ends from accessing the encrypted passwords. Note
also that any shell back-ends will run as the specified non-privileged
user.
-t slapd 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 terminal and start
serving the LDAP databases defined in the default config file, just
type:
/opt/local/libexec/slapd
To start slapd with an alternate configuration file, and turn on volu-
minous debugging which will be printed on standard error, type:
/opt/local/libexec/slapd -f /var/tmp/slapd.conf -d 255
To test whether the configuration file is correct or not, type:
/opt/local/libexec/slapd -t
