4H1: Running slapd
5
6{{slapd}}(8) is designed to be run as a standalone service.  This
7allows the server to take advantage of caching, manage concurrency
8issues with underlying databases, and conserve system resources.
9Running from {{inetd}}(8) is {{NOT}} an option.
10
11
12H2: Command-Line Options
13
14{{slapd}}(8) supports a number of command-line options as detailed
15in the manual page.  This section details a few commonly used options.
16
17>	-f <filename>
18
19This option specifies an alternate configuration file for slapd.
20The default is normally {{F:/usr/local/etc/openldap/slapd.conf}}.
21
22>	-F <slapd-config-directory>
23
24Specifies the slapd configuration directory. The default is {{F:/usr/local/etc/openldap/slapd.d}}.
25
26If both {{EX:-f}} and {{EX:-F}} are specified, the config file will be read and converted 
27to config directory format and written to the specified directory.  
28If neither option is specified, slapd will attempt to read the default config 
29directory before trying to use the default config file. If a valid config 
30directory exists then the default config file is ignored. All of the slap tools 
31that use the config options observe this same behavior.
32
33>	-h <URLs>
34
35This option specifies alternative listener configurations.  The
36default is {{EX:ldap:///}} which implies {{TERM:LDAP}} over
37{{TERM:TCP}} on all interfaces on the default LDAP port 389.  You
38can specify specific host-port pairs or other protocol schemes (such
39as {{EX:ldaps://}} or {{EX:ldapi://}}).
40
41!block table
42URL        Protocol        Transport
43ldap:///   LDAP            TCP port 389
44ldaps:///  LDAP over SSL   TCP port 636
45ldapi:///  LDAP            IPC (Unix-domain socket)
46!endblock
47
48For example, {{EX:-h
49"ldaps:// ldap://127.0.0.1:666"}} will create two listeners: one
50for the (non-standard) {{EX:ldaps://}} scheme on all interfaces on
51the default {{EX:ldaps://}} port 636, and one for the standard
52{{EX:ldap://}} scheme on the {{EX:localhost}} ({{loopback}}) interface
53on port 666.  Hosts may be specified using using hostnames or
54{{TERM:IPv4}} or {{TERM:IPv6}} addresses.  Port values must be
55numeric.
56
57For LDAP over IPC, the pathname of the Unix-domain socket can be encoded
58in the URL. Note that directory separators must be 
59URL-encoded, like any other characters that are special to URLs.
60Thus the socket {{EX:/usr/local/var/ldapi}} must be encoded as
61
62>	ldapi://%2Fusr%2Flocal%2Fvar%2Fldapi
63
64ldapi: is described in detail in {{Using LDAP Over IPC Mechanisms}} [{{REF:Chu-LDAPI}}]
65
66Note that the ldapi:/// transport is not widely implemented: non-OpenLDAP clients
67may not be able to use it.
68
69>	-n <service-name>
70
71This option specifies the service name used for logging and
72other purposes. The default service name is {{EX:slapd}}.
73
74>	-l <syslog-local-user>
75
76This option specifies the local user for the {{syslog}}(8)
77facility.  Values can be {{EX:LOCAL0}}, {{EX:LOCAL1}}, {{EX:LOCAL2}}, ...,
78and {{EX:LOCAL7}}.  The default is {{EX:LOCAL4}}.  This option
79may not be supported on all systems.
80
81>	-u user -g group
82
83These options specify the user and group, respectively, to run
84as.  {{EX:user}} can be either a user name or uid.  {{EX:group}}
85can be either a group name or gid.
86
87>	-r directory
88
89This option specifies a run-time directory.  slapd will
90{{chroot}}(2) to this directory after opening listeners but
91before reading any configuration files or initializing
92any backends.
93.
94
95>	-d <level> | ?
96
97This option sets the slapd debug level to <level>. When level is a
98`?' character, the various debugging levels are printed and slapd
99exits, regardless of any other options you give it. Current
100debugging levels are
101
102!block table; colaligns="RL"; align=Center; \
103	title="Table 7.1: Debugging Levels"
104Level	Keyword		Description
105-1	any		enable all debugging
1060			no debugging
1071	(0x1 trace)	trace function calls
1082	(0x2 packets)	debug packet handling
1094	(0x4 args)	heavy trace debugging
1108	(0x8 conns)	connection management
11116	(0x10 BER)	print out packets sent and received
11232	(0x20 filter)	search filter processing
11364	(0x40 config)	configuration processing
114128	(0x80 ACL)	access control list processing
115256	(0x100 stats)	stats log connections/operations/results
116512	(0x200 stats2)	stats log entries sent
1171024	(0x400 shell)	print communication with shell backends
1182048	(0x800 parse)	print entry parsing debugging
11916384	(0x4000 sync)	syncrepl consumer processing
12032768	(0x8000 none)	only messages that get logged whatever log level is set
121!endblock
122
123You may enable multiple levels by specifying the debug option once for each desired level.  Or, since debugging levels are additive, you can do the math yourself. That is, if you want to trace function calls and watch the config file being processed, you could set level to the sum of those two levels (in this case, {{EX: -d 65}}).  Or, you can let slapd do the math, (e.g. {{EX: -d 1 -d 64}}).  Consult {{F: <ldap_log.h>}} for more details.
124
125Note: slapd must have been compiled with {{EX:--enable-debug}}
126defined for any debugging information beyond the two stats levels
127to be available (the default).
128
129
130H2: Starting slapd
131
132In general, slapd is run like this:
133
134>	/usr/local/libexec/slapd [<option>]*
135
136where {{F:/usr/local/libexec}} is determined by {{EX:configure}}
137and <option> is one of the options described above (or in {{slapd}}(8)).
138Unless you have specified a debugging level (including level {{EX:0}}),
139slapd will automatically fork and detach itself from its controlling
140terminal and run in the background.
141
142H2: Stopping slapd
143
144To kill off {{slapd}}(8) safely, you should give a command like this
145
146> 	kill -INT `cat /usr/local/var/slapd.pid`
147
148where {{F:/usr/local/var}} is determined by {{EX:configure}}.
149
150Killing slapd by a more drastic method may cause information loss or
151database corruption.
