15 Slapd is the stand-alone LDAP daemon. It listens for LDAP connections
16 on any number of ports (default 389), responding to the LDAP operations
17 it receives over these connections. slapd is typically invoked at boot
18 time, usually out of /etc/rc.local. Upon startup, slapd normally forks
19 and disassociates itself from the invoking tty. If configured in the
20 config file (or config directory), the slapd process will print its
21 process ID (see getpid(2)) to a .pid file, as well as the command line
22 options during invocation to an .args file (see slapd.conf(5)). If the
23 -d flag is given, even with a zero argument, slapd will not fork and
24 disassociate from the invoking tty.
25 Slapd can be configured to provide replicated service for a database
27 with the help of slurpd, the standalone LDAP update replication daemon.
28 See slurpd(8) for details.
29 See the "OpenLDAP Administrator's Guide" for more details on slapd.

33 -4 Listen on IPv4 addresses only.
34 -6 Listen on IPv6 addresses only.
36 -T {a|c|d|i|p|t|acl|auth}
38 Run in Tool mode. The additional argument selects whether to run
39 as slapadd, slapcat, slapdn, slapindex, slappasswd, or slaptest
40 (slapacl and slapauth need the entire "acl" and "auth" option
41 value to be spelled out, as "a" is reserved to slapadd). This
42 option should be the first option specified when it is used; any
43 remaining options will be interpreted by the corresponding slap
44 tool program, according to the respective man pages. Note that
45 these tool programs will usually be symbolic links to slapd.
46 This option is provided for situations where symbolic links are
47 not provided or not usable.
48 -d debug-level
50 Turn on debugging as defined by debug-level. If this option is
51 specified, even with a zero argument, slapd will not fork or
52 disassociate from the invoking terminal. Some general operation
53 and status messages are printed for any value of debug-level.
54 debug-level is taken as a bit string, with each bit correspond‐
55 ing to a different kind of debugging information. See
56 <ldap_log.h> for details. Remember that if you turn on packet
57 logging, packets containing bind passwords will be output, so if
58 you redirect the log to a logfile, that file should be read-pro‐
59 tected.
60 -s syslog-level
62 This option tells slapd at what level debugging statements
63 should be logged to the syslog(8) facility.
64 -n service-name
66 Specifies the service name for logging and other purposes.
67 Defaults to basename of argv[0], i.e.: "slapd".
68 -l syslog-local-user
70 Selects the local user of the syslog(8) facility. Value can be
71 LOCAL0, through LOCAL7, as well as USER and DAEMON. The default
72 is LOCAL4. However, this option is only permitted on systems
73 that support local users with the syslog(8) facility.
74 -f slapd-config-file
76 Specifies the slapd configuration file. The default is
77 /etc/openldap/slapd.conf.
78 -F slapd-config-directory
80 Specifies the slapd configuration directory. The default is
81 /etc/openldap/slapd.d. If both -f and -F are specified, the
82 config file will be read and converted to config directory for‐
83 mat and written to the specified directory. If neither option
84 is specified, slapd will attempt to read the default config
85 directory before trying to use the default config file. If a
86 valid config directory exists then the default config file is
87 ignored. All of the slap tools that use the config options
88 observe this same behavior.
89 -h URLlist
91 slapd will by default serve ldap:/// (LDAP over TCP on all
92 interfaces on default LDAP port). That is, it will bind using
93 INADDR_ANY and port 389. The -h option may be used to specify
94 LDAP (and other scheme) URLs to serve. For example, if slapd is
95 given -h "ldap://127.0.0.1:9009/ ldaps:/// ldapi:///", it will
96 listen on 127.0.0.1:9009 for LDAP, 0.0.0.0:636 for LDAP over
97 TLS, and LDAP over IPC (Unix domain sockets). Host 0.0.0.0 rep‐
98 resents INADDR_ANY (any interface). A space separated list of
99 URLs is expected. The URLs should be of the LDAP, LDAPS, or
100 LDAPI schemes, and generally without a DN or other optional
101 parameters (excepting as discussed below). Support for the lat‐
102 ter two schemes depends on selected configuration options.
103 Hosts may be specified by name or IPv4 and IPv6 address formats.
104 Ports, if specified, must be numeric. The default ldap:// port
105 is 389 and the default ldaps:// port is 636.
106 The listener permissions are indicated by "x-mod=-rwxrwxrwx",
108 "x-mod=0777" or "x-mod=777", where any of the "rwx" can be "-"
109 to suppress the related permission, while any of the "7" can be
110 any legal octal digit, according to chmod(1). The listeners can
111 take advantage of the "x-mod" extension to apply rough limita‐
112 tions to operations, e.g. allow read operations ("r", which
113 applies to search and compare), write operations ("w", which
114 applies to add, delete, modify and modrdn), and execute opera‐
115 tions ("x", which means bind is required). "User" permissions
116 apply to authenticated users, while "other" apply to anonymous
117 users; "group" permissions are ignored. For example,
118 "ldap:///????x-mod=-rw-------" means that read and write is only
119 allowed for authenticated connections, and bind is required for
120 all operations. This feature is experimental, and requires to
121 be manually enabled at configure time.
122 -r directory
124 Specifies a directory to become the root directory. slapd will
125 change the current working directory to this directory and then
126 chroot(2) to this directory. This is done after opening listen‐
127 ers but before reading any configuration file or initializing
128 any backend. When used as a security mechanism, it should be
129 used in conjunction with -u and -g options.
130 -u user
132 slapd will run slapd with the specified user name or id, and
133 that user's supplementary group access list as set with init‐
134 groups(3). The group ID is also changed to this user's gid,
135 unless the -g option is used to override. Note when used with
136 -r, slapd will use the user database in the change root environ‐
137 ment.
138 Note that on some systems, running as a non-privileged user will
140 prevent passwd back-ends from accessing the encrypted passwords.
141 Note also that any shell back-ends will run as the specified
142 non-privileged user.
143 -g group
145 slapd will run with the specified group name or id. Note when
146 used with -r, slapd will use the group database in the change
147 root environment.
148 -c cookie
150 This option provides a cookie for the syncrepl replication con‐
151 sumer. The cookie is a comma separated list of name=value
152 pairs. Currently supported syncrepl cookie fields are rid and
153 csn. rid identifies a replication thread within the consumer
154 server and is used to find the syncrepl specification in
155 slapd.conf(5) having the matching replication identifier in its
156 definition. The rid must be provided in order for any other
157 specified values to be used. csn is the commit sequence number
158 received by a previous synchronization and represents the state
159 of the consumer replica content which the syncrepl engine will
160 synchronize to the current provider content.

163 To start slapd and have it fork and detach from the terminal and start
164 serving the LDAP databases defined in the default config file, just
165 type:
166 /usr/lib64/slapd
168 To start slapd with an alternate configuration file, and turn on volu‐
170 minous debugging which will be printed on standard error, type:
171 /usr/lib64/slapd -f /var/tmp/slapd.conf -d 255
173 To test whether the configuration file is correct or not, type:
175 /usr/lib64/slapd -Tt
