.SH NAME
-ldap.conf, .ldaprc \- ldap configuration file
+ldap.conf, .ldaprc \- LDAP configuration file/environment variables
.SH SYNOPSIS
-ETCDIR/ldap.conf, .ldaprc
+ETCDIR/ldap.conf, ldaprc, .ldaprc, $LDAP<option-name>
.SH DESCRIPTION
If the environment variable \fBLDAPNOINIT\fP is defined, all
defaulting is disabled.
For example, to define \fBBASE\fP via the environment, set the variable
\fBLDAPBASE\fP to the desired value.
.LP
-Some options are user\-only. Such options are ignored if present
+Some options are user-only. Such options are ignored if present
in the
.I ldap.conf
(or file specified by
.BR LDAPCONF ).
+.LP
+Thus the following files and variables are read, in order:
+.nf
+ variable $LDAPNOINIT, and if that is not set:
+ system file ETCDIR/ldap.conf,
+ user files $HOME/ldaprc, $HOME/.ldaprc, ./ldaprc,
+ system file $LDAPCONF,
+ user files $HOME/$LDAPRC, $HOME/.$LDAPRC, ./$LDAPRC,
+ variables $LDAP<option-name>.
+.fi
+Settings late in the list override earlier ones.
.SH OPTIONS
The configuration options are case-insensitive;
their value, on a case by case basis, may be case-sensitive.
+.LP
+Blank lines and lines beginning with a hash mark (`#')
+are ignored up to their end.
+.LP
+Valid lines are made of an option's name (a sequence of non-blanks,
+conventionally written in uppercase, although not required),
+followed by a value.
+The value starts with the first non-blank character after
+the option's name, and terminates at the end of the line,
+or at the last sequence of blanks before the end of the line.
+The tokenization of the value, if any, is delegated to the handler(s)
+for that option, if any. Quoting values that contain blanks
+may be incorrect, as the quotes would become part of the value.
+For example,
+
+ URI "ldap:// ldaps://"
+
+is incorrect, while
+
+ URI ldap:// ldaps://
+
+is correct (note the absence of the double quotes).
+.LP
+A line cannot be longer than LINE_MAX, which should be more than 2000 bytes
+on all platforms.
+There is no mechanism to split a long line on multiple lines, either for
+beautification or to overcome the above limit.
+.LP
The different configuration options are:
.TP
-.B URI <ldap[s]://[name[:port]] ...>
+.B URI <ldap[si]://[name[:port]] ...>
Specifies the URI(s) of an LDAP server(s) to which the
.I LDAP
-library should connect. The URI scheme may be either
-.B ldap
-or
+library should connect. The URI scheme may be any of
+.BR ldap ,
.B ldaps
-which refer to LDAP over TCP and LDAP over SSL (TLS) respectively.
+or
+.BR ldapi ,
+which refer to LDAP over TCP, LDAP over SSL (TLS) and LDAP
+over IPC (UNIX domain sockets), respectively.
Each server's name can be specified as a
domain-style name or an IP address literal. Optionally, the
server's name can followed by a ':' and the port number the LDAP
server is listening on. If no port number is provided, the default
port for the scheme is used (389 for ldap://, 636 for ldaps://).
+For LDAP over IPC,
+.B name
+is the name of the socket, and no
+.B port
+is required, nor allowed; note that directory separators must be
+URL-encoded, like any other characters that are special to URLs;
+so the socket
+
+ /usr/local/var/ldapi
+
+must be specified as
+
+ ldapi://%2Fusr%2Flocal%2Fvar%2Fldapi
+
A space separated list of URIs may be provided.
