.SH NAME
ldap.conf, .ldaprc \- ldap configuration file
.SH SYNOPSIS
ETCDIR/ldap.conf
\fP.ldaprc\fP
.SH DESCRIPTION
The
.I ldap.conf
configuration file is used to set system-wide defaults to be applied when
running
.I ldap
clients. If the environment variable \fBLDAPNOINIT\fP is defined, all
defaulting is disabled.
.LP
Each user may specify an optional configuration file,
.IR .ldaprc ,
in his/her home directory which will be used to override the system-wide
defaults file.
.LP
Additional configuration files can be specified using
the \fBLDAPCONF\fP and \fBLDAPRC\fP environment variables.
\fBLDAPCONF\fP may be set the path of a configuration file. This
path can be absolute or relative to current working directory.
The \fBLDAPRC\fP, if defined, should be a basename of a file
in the current working directory or in the user's home directory.
.LP
Environmental variables may also be used to augment the file based defaults.
The name of the option is the as listed but with a prefix of \fBLDAP\fP.
For example, to define \fBBASE\fP via the environment, define the variable
\fBLDAPBASE\fP to desired value.
.LP
Some options are user\-only. Such options are ignored if present
in the
.IR ldap.conf
(or file specified by
.BR LDAPCONF ).
.SH OPTIONS
The different configuration options are:
.TP 1i
\fBBASE <base>\fP
Used to specify the default base DN to use when performing ldap operations.
The base must be specified as a Distinguished Name in LDAP format.
.TP 1i
\fBBINDDN <dn>\fP
Used to specify the default bind DN to use when performing ldap operations.
The bind DN must be specified as a Distinguished Name in LDAP format.
This is a user\-only option.
.TP 1i
\fBHOST <name[:port] ...>\fP
Used to specify the name(s) of an LDAP server(s) to which
.I ldap
library should connect to. Each server's name can be specified as a
domain-style name or an IP address and optionally followed a ':' and
the port number the ldap server is listening on. A space separated
listed of host may be provided.
.TP 1i
\fBPORT <port>\fP
Used to specify the port used with connecting to LDAP servers(s).
The port may be specified as a number.
.TP 1i
\fBSASL_SECPROPS <properties>\fP
Used to specify Cyrus SASL security properties.
The
.B none
flag (without any other properities) causes the flag properites
defaults ("noanonymous,noplain") to be cleared.
The
.B noplain
flag disables mechanisms susceptible to simple passive attacks.
The
.B noactive
flag disables mechanisms susceptible to active attacks.
The
.B nodict
flag disables mechanisms susceptible to passive dictionary attacks.
The
.B noanonyous
flag disables mechanisms which support anonymous login.
The
.B forwardsec
flag require forward secrecy between sessions.
The
.B passcred
require mechanisms which pass client credentials (and allow
mechanisms which can pass credentials to do so).
The
.B minssf=<factor>
property specifies the minimum acceptable
.I security strength factor
as an integer approximate to effective key length used for
encryption. 0 (zero) implies no protection, 1 implies integrity
protection only, 56 allows DES or other weak ciphers, 112
allows triple DES and other strong ciphers, 128 allows RC4,
Blowfish and other modern strong ciphers. The default is 0.
The
.B maxssf=<factor>
property specifies the maximum acceptable
.I security strength factor
as an integer (see minssf description). The default is INT_MAX.
The
.B maxbufsize=<factor>
property specifies the maximum security layer receive buffer
size allowed. 0 disables security layers. The default is 65536.
.TP 1i
\fBSIZELIMIT <integer>\fP
Used to specify a size limit to use when performing searches. The
number should be an non-negative integer. \fISIZELIMIT\fP of zero (0)
specifies unlimited search size.
.TP 1i
\fBTIMELIMIT <integer>\fP
Used to specify a time limit to use when performing searches. The
number should be an non-negative integer. \fITIMELIMIT\fP of zero (0)
specifies unlimited search time to be used.
.TP 1i
\fBDEREF <never|searching|finding|always>\fP
Specify how aliases dereferencing is done. \fIDEREF\fP should
be set to one of
.B never,
.B always,
.B search,
or
.B find
to specify that aliases are never dereferenced, always dereferenced,
dereferenced when searching, or dereferenced only when locating the
base object for the search. The default is to never dereference aliases.
