22 is the stand-alone LDAP daemon. It listens for LDAP connections on
23 any number of ports (default 389), responding
24 to the LDAP operations it receives over these connections.

66 Listen on IPv6 addresses only.
69 Run in Tool mode. The additional argument selects whether to run as
70 slapadd, slapcat, slapindex, or slappasswd. This option should be the first
71 option specified when it is used. Any remaining options will be interpreted
72 by the corresponding slap tool program. Note that these tool programs will
73 usually be symbolic links to slapd. This option is provided for situations
74 where symbolic links are not provided or not usable.

79 If this option is specified, even with a zero argument,
81 will not fork or disassociate from the invoking terminal. Some general
82 operation and status messages are printed for any value of \fIdebug\-level\fP.
83 \fIdebug\-level\fP is taken as a bit string, with each bit corresponding to a
84 different kind of debugging information. See <ldap.h> for details.

96 .BI \-n " service\-name"
97 Specifies the service name for logging and other purposes. Defaults
98 to basename of argv[0], i.e.: "slapd".

101 Selects the local user of the

121 will by default serve
123 (LDAP over TCP on all interfaces on default LDAP port). That is,
124 it will bind using INADDR_ANY and port 389.
127 option may be used to specify LDAP (and other scheme) URLs to serve.
128 For example, if slapd is given
129 .B "\-h \(dqldap://127.0.0.1:9009/ ldaps:/// ldapi:///\(dq",
130 It will bind 127.0.0.1:9009 for LDAP, 0.0.0.0:636 for LDAP over TLS,
131 and LDAP over IPC (Unix domain sockets). Host 0.0.0.0 represents
133 A space separated list of URLs is expected. The URLs should be of
134 LDAP (ldap://) or LDAP over TLS (ldaps://) or LDAP over IPC (ldapi://)
135 scheme without a DN or other optional parameters, except an experimental
136 extension to indicate the permissions of the underlying listeners.
137 Support for the latter two schemes depends on selected configuration
138 options. Hosts may be specified by name or IPv4 and IPv6 address formats.
139 Ports, if specified, must be numeric. The default ldap:// port is 389
140 and the default ldaps:// port is 636.
141 The socket permissions for LDAP over IPC are indicated by
142 "x-mod=-rwxrwxrwx", "x-mod=0777" or "x-mod=777", where any
143 of the "rwx" can be "-" to suppress the related permission (note,
144 however, that sockets only honor the "w" permission), while any
145 of the "7" can be any legal octal digit, according to chmod(1).
146 While LDAP over IPC requires write permissions on the socket to allow
147 any operation, the other listeners can take advantage of the "x-mod"
148 extension to apply rough limitations to users, e.g. allow read operations
149 ("r", which applies to search and compare), write operations ("w",
150 which applies to add, delete, modify and modrdn), and execute operations
151 ("x", which means bind is required).
152 "User" permissions apply to bound users, while "other" apply

161 any configuration file or initializing any backend.
165 will run slapd with the specified user name or id, and that user's
166 supplementary group access list as set with initgroups(3). The group ID

174 Note that on some systems, running as a non-privileged user will prevent
175 passwd back-ends from accessing the encrypted passwords. Note also that
176 any shell back-ends will run as the specified non-privileged user.

181 \fI\-f\fP switch) and check its syntax, without opening any listener

186 The cookie is a comma separated list of name=value pairs.

195 syncrepl engine will synchronize to the current provider content.
197 is the identity of the per-scope session log with which the
198 provider server can process this syncrepl request to reduce
