11 If the environment variable \fBLDAPNOINIT\fP is defined, all
12 defaulting is disabled.
16 configuration file is used to set system-wide defaults to be applied when
21 Users may create an optional configuration file,
25 in their home directory which will be used to override the system-wide
29 in the current working directory is also used.
32 Additional configuration files can be specified using
33 the \fBLDAPCONF\fP and \fBLDAPRC\fP environment variables.
34 \fBLDAPCONF\fP may be set to the path of a configuration file. This
35 path can be absolute or relative to the current working directory.
36 The \fBLDAPRC\fP, if defined, should be the basename of a file
37 in the current working directory or in the user's home directory.
39 Environmental variables may also be used to augment the file based defaults.
40 The name of the variable is the option name with an added prefix of \fBLDAP\fP.
41 For example, to define \fBBASE\fP via the environment, set the variable
42 \fBLDAPBASE\fP to the desired value.
44 Some options are user\-only. Such options are ignored if present
50 The different configuration options are:
52 .B URI <ldap[s]://[name[:port]] ...>
53 Specifies the URI(s) of an LDAP server(s) to which the
55 library should connect. The URI scheme may be either
58 which refer to LDAP over TCP and LDAP over SSL (TLS) respectively.
59 Each server's name can be specified as a
60 domain-style name or an IP address literal. Optionally, the
61 server's name can followed by a ':' and the port number the LDAP
62 server is listening on. If no port number is provided, the default
63 port for the scheme is used (389 for ldap://, 636 for ldaps://).
64 A space separated list of URIs may be provided.
67 Specifies the default base DN to use when performing ldap operations.
68 The base must be specified as a Distinguished Name in LDAP format.
71 Specifies the default bind DN to use when performing ldap operations.
72 The bind DN must be specified as a Distinguished Name in LDAP format.
73 This is a user\-only option.
75 .B HOST <name[:port] ...>
76 Specifies the name(s) of an LDAP server(s) to which the
78 library should connect. Each server's name can be specified as a
79 domain-style name or an IP address and optionally followed by a ':' and
80 the port number the ldap server is listening on. A space separated
81 list of hosts may be provided.
83 is deprecated in favor of
87 Specifies the default port used when connecting to LDAP servers(s).
88 The port may be specified as a number.
90 is deprecated in favor of
93 .B SIZELIMIT <integer>
94 Specifies a size limit to use when performing searches. The
95 number should be a non-negative integer. \fISIZELIMIT\fP of zero (0)
96 specifies unlimited search size.
98 .B TIMELIMIT <integer>
99 Specifies a time limit to use when performing searches. The
100 number should be a non-negative integer. \fITIMELIMIT\fP of zero (0)
101 specifies unlimited search time to be used.
104 Specifies how alias dereferencing is done when performing a search. The
106 can be specified as one of the following keywords:
110 Aliases are never dereferenced. This is the default.
113 Aliases are dereferenced in subordinates of the base object, but
114 not in locating the base object of the search.
117 Aliases are only dereferenced when locating the base object of the search.
120 Aliases are dereferenced both in searching and in locating the base object
124 If OpenLDAP is built with Simple Authentication and Security Layer support,
125 there are more options you can specify.
127 .B SASL_MECH <mechanism>
128 Specifies the SASL mechanism to use.
129 This is a user\-only option.
131 .B SASL_REALM <realm>
132 Specifies the SASL realm.
133 This is a user\-only option.
135 .B SASL_AUTHCID <authcid>
136 Specifies the authentication identity.
137 This is a user\-only option.
139 .B SASL_AUTHZID <authcid>
140 Specifies the proxy authorization identity.
141 This is a user\-only option.
143 .B SASL_SECPROPS <properties>
144 Specifies Cyrus SASL security properties. The
146 can be specified as a comma-separated list of the following:
150 (without any other properties) causes the properties
151 defaults ("noanonymous,noplain") to be cleared.
154 disables mechanisms susceptible to simple passive attacks.
157 disables mechanisms susceptible to active attacks.
160 disables mechanisms susceptible to passive dictionary attacks.
163 disables mechanisms which support anonymous login.
166 requires forward secrecy between sessions.
169 requires mechanisms which pass client credentials (and allows
170 mechanisms which can pass credentials to do so).
173 specifies the minimum acceptable
174 .I security strength factor
175 as an integer approximating the effective key length used for
176 encryption. 0 (zero) implies no protection, 1 implies integrity
177 protection only, 56 allows DES or other weak ciphers, 112
178 allows triple DES and other strong ciphers, 128 allows RC4,
179 Blowfish and other modern strong ciphers. The default is 0.
182 specifies the maximum acceptable
183 .I security strength factor
186 description). The default is
189 .B maxbufsize=<factor>
190 specifies the maximum security layer receive buffer
191 size allowed. 0 disables security layers. The default is 65536.
194 If OpenLDAP is built with Transport Layer Security support, there
195 are more options you can specify. These options are used when an
197 is selected (by default or otherwise) or when the application
198 negotiates TLS by issuing the LDAP Start TLS operation.
200 .B TLS_CACERT <filename>
201 Specifies the file that contains certificates for all of the Certificate
202 Authorities the client will recognize.
204 .B TLS_CACERTDIR <path>
205 Specifies the path of a directory that contains Certificate Authority
206 certificates in separate individual files. The
208 is always used before
211 .B TLS_CERT <filename>
212 Specifies the file that contains the client certificate.
213 This is a user\-only option.
215 .B TLS_KEY <filename>
216 Specifies the file that contains the private key that matches the certificate
219 file. Currently, the private key must not be protected with a password, so
220 it is of critical importance that the key file is protected carefully. This
221 is a user\-only option.
223 .B TLS_RANDFILE <filename>
224 Specifies the file to obtain random bits from when /dev/[u]random is
225 not available. Generally set to the name of the EGD/PRNGD socket.
226 The environment variable RANDFILE can also be used to specify the filename.
228 .B TLS_REQCERT <level>
229 Specifies what checks to perform on server certificates in a TLS session,
232 can be specified as one of the following keywords:
236 The client will not request or check any server certificate.
239 The server certificate is requested. If no certificate is provided,
240 the session proceeds normally. If a bad certificate is provided, it will
241 be ignored and the session proceeds normally.
244 The server certificate is requested. If no certificate is provided,
245 the session proceeds normally. If a bad certificate is provided,
246 the session is immediately terminated.
249 These keywords are equivalent. The server certificate is requested. If no
250 certificate is provided, or a bad certificate is provided, the session
251 is immediately terminated. This is the default setting.
