6 {{slapd}}(8) is designed to be run as a standalone service. This
7 allows the server to take advantage of caching, manage concurrency
8 issues with underlying databases, and conserve system resources.
9 Running from {{inetd}}(8) is {{NOT}} an option.
12 H2: Command-Line Options
14 {{slapd}}(8) supports a number of command-line options as detailed
15 in the manual page. This section details a few commonly used options.
19 This option specifies an alternate configuration file for slapd.
20 The default is normally {{F:/usr/local/etc/openldap/slapd.conf}}.
22 > -F <slapd-config-directory>
24 Specifies the slapd configuration directory. The default is {{F:/usr/local/etc/openldap/slapd.d}}
26 If both {{EX:-f}} and {{EX:-F}} are specified, the config file will be read and converted
27 to config directory format and written to the specified directory.
28 If neither option is specified, slapd will attempt to read the default config
29 directory before trying to use the default config file. If a valid config
30 directory exists then the default config file is ignored. All of the slap tools
31 that use the config options observe this same behavior.
35 This option specifies alternative listener configurations. The
36 default is {{EX:ldap:///}} which implies {{TERM:LDAP}} over
37 {{TERM:TCP}} on all interfaces on the default LDAP port 389. You
38 can specify specific host-port pairs or other protocol schemes (such
39 as {{EX:ldaps://}} or {{EX:ldapi://}}). For example, {{EX:-h
40 "ldaps:// ldap://127.0.0.1:666"}} will create two listeners: one
41 for the (non-standard) {{EX:ldaps://}} scheme on all interfaces on
42 the default {{EX:ldaps://}} port 636, and one for the standard
43 {{EX:ldap://}} scheme on the {{EX:localhost}} ({{loopback}}) interface
44 on port 666. Hosts may be specified using using hostnames or
45 {{TERM:IPv4}} or {{TERM:IPv6}} addresses. Port values must be
50 This option specifies the service name used for logging and
51 other purposes. The default service name is {{EX:slapd}}.
53 > -l <syslog-local-user>
55 This option specifies the local user for the {{syslog}}(8)
56 facility. Values can be {{EX:LOCAL0}}, {{EX:LOCAL1}}, {{EX:LOCAL2}}, ...,
57 and {{EX:LOCAL7}}. The default is {{EX:LOCAL4}}. This option
58 may not be supported on all systems.
62 These options specify the user and group, respectively, to run
63 as. {{EX:user}} can be either a user name or uid. {{EX:group}}
64 can be either a group name or gid.
68 This option specifies a run-time directory. slapd will
69 {{chroot}}(2) to this directory after opening listeners but
70 before reading any configuration files or initializing
76 This option sets the slapd debug level to <level>. When level is a
77 `?' character, the various debugging levels are printed and slapd
78 exits, regardless of any other options you give it. Current
81 !block table; colaligns="RL"; align=Center; \
82 title="Table 7.1: Debugging Levels"
84 -1 enable all debugging
86 1 trace function calls
87 2 debug packet handling
88 4 heavy trace debugging
89 8 connection management
90 16 print out packets sent and received
91 32 search filter processing
92 64 configuration file processing
93 128 access control list processing

97 2048 print entry parsing debugging
100 You may enable multiple levels by specifying the debug option
101 once for each desired level. Or, since debugging levels are
102 additive, you can do the math yourself. That is, if you want
103 to trace function calls and watch the config file being
104 processed, you could set level to the sum of those two levels
105 (in this case, {{EX: -d 65}}). Or, you can let slapd do the
106 math, (e.g. {{EX: -d 1 -d 64}}). Consult {{F: <ldap_log.h>}} for
109 Note: slapd must have been compiled with {{EX:-DLDAP_DEBUG}}
110 defined for any debugging information beyond the two stats levels
116 In general, slapd is run like this:
118 > /usr/local/libexec/slapd [<option>]*
120 where {{F:/usr/local/libexec}} is determined by {{EX:configure}}
121 and <option> is one of the options described above (or in {{slapd}}(8)).
122 Unless you have specified a debugging level (including level {{EX:0}}),
123 slapd will automatically fork and detach itself from its controlling
124 terminal and run in the background.
128 To kill off {{slapd}}(8) safely, you should give a command like this
130 > kill -INT `cat /usr/local/var/slapd.pid`
132 where {{F:/usr/local/var}} is determined by {{EX:configure}}.
134 Killing slapd by a more drastic method may cause information loss or
