NAME
slapd - Stand-alone LDAP Daemon
SYNOPSIS
slapd [-[4|6]] [-d debug-level]
[-f slapd-config-file] [-h URLs] [-n
service-name] [-s syslog-level] [-l syslog-local-user]
[-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),
responding to the LDAP operations it receives over these
connections. slapd is typically invoked at boot time,
(for Unix/Linux) usually out of /etc/rc.local. Upon startup, slapd
normally forks and disassociates itself from the invoking tty.
If configured in /usr/local/etc/slapd.conf, the slapd
process will print its process ID 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 "aeSLAPD Administrator's Guide" for more
details on slapd.
OPTIONS
- -4
- Listen on IPv4 addresses only.
- -6
- Listen on IPv6 addresses only (Future).
- -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.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.
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 /usr/local/etc/slapd.conf
or the file designated in SDIR.INI.
- -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 dqldap://127.0.0.1:9009/
ldaps:/// ldapi:///dq, 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 configuration 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 yjr Unix/Linux chmod.
- -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.
- -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:
slapd
To start slapd with an alternate configuration file,
and turn on voluminous debugging which will be printed on
standard error, type:
slapd -f slapd.conf -d 255
To test whether the configuration file is correct or not, type:
slapd -t
