NAME
slapd - Stand-alone LDAP Daemon
SYNOPSIS
/usr/internet/openldap/libexec/slapd [-[4|6]] [-T
{acl|add|auth|cat|dn|index|passwd|test}] [-d debug-level] [-f
slapd-config-file] [-F slapd-config-directory] [-h URLs] [-n service-name]
[-s syslog-level] [-l syslog-local-user] [-r directory] [-u user] [-g
group] [-c cookie]
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 the config
file (or config directory), 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|d|i|p|t|acl|auth}
Run in Tool mode. The additional argument selects whether to run as
slapadd, slapcat, slapdn, slapindex, slappasswd, or slaptest (slapacl
and slapauth need the entire "acl" and "auth" option value to be
spelled out, as "a" is reserved to slapadd). This option should be
the first option specified when it is used; any remaining options will
be interpreted by the corresponding slap tool program, according to
the respective man pages. Note that these tool programs will usually
be symbolic 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 corresponding to a different
kind of debugging information. See <ldap_log.h> for details.
Remember that if you turn on packet logging, packets 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.
-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. Value can be LOCAL0,
through LOCAL7, as well as USER and DAEMON. 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
/usr/internet/openldap/etc/slapd.conf.
-F slapd-config-directory
Specifies the slapd configuration directory. The default is
/usr/internet/openldap/etc/slapd.d. 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, slapd will attempt to read the default config directory
before trying to use the default config file. If a valid config
directory exists then the default config file is ignored. All of the
slap tools that use the config options observe this same behavior.
-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 listen on
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 (any
interface). A space separated list of URLs is expected. The URLs
should be of the LDAP, LDAPS, or LDAPI schemes, and generally 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 listener permissions 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, while any of the "7" can be any legal
octal digit, according to chmod(1). The listeners can take advantage
of the "x-mod" extension to apply rough limitations to operations,
e.g. allow read operations ("r", which applies to search and compare),
write operations ("w", which applies to add, delete, modify and
modrdn), and execute operations ("x", which means bind is required).
"User" permissions apply to authenticated users, while "other" apply
to anonymous users; "group" permissions are ignored. For example,
"ldap:///????x-mod=-rw-------" means that read and write is only
allowed for authenticated connections, and bind is required for all
operations. This feature is experimental, and requires to be manually
enabled at configure time.
-r directory
Specifies a directory to become the root directory. slapd will change
the current working directory to this directory and then chroot(2) to
this directory. This is done after opening listeners but before
reading any configuration file or initializing any backend. When used
as a security mechanism, it should be used in conjunction with -u and
-g options.
-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. Note when used with -r, slapd will use the user
database in the change root environment.
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.
-g group
slapd will run with the specified group name or id. Note when used
with -r, slapd will use the group database in the change root
environment.
-c cookie
This option provides a cookie for the syncrepl replication consumer.
The cookie is a comma separated list of name=value pairs. Currently
supported syncrepl cookie fields are rid and csn. rid identifies a
replication thread within the consumer server and is used to find the
syncrepl specification in slapd.conf(5) having the matching
replication identifier in its definition. The rid must be provided in
order for any other specified values to be used. csn is the commit
sequence number received by a previous synchronization and represents
the state of the consumer replica content which the syncrepl engine
will synchronize to the current provider content.
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:
/usr/internet/openldap/libexec/slapd
To start slapd with an alternate configuration file, and turn on voluminous
debugging which will be printed on standard error, type:
/usr/internet/openldap/libexec/slapd -f /var/tmp/slapd.conf -d 255
To test whether the configuration file is correct or not, type:
/usr/internet/openldap/libexec/slapd -Tt
