MAPS
Currently, few maps are builtin but additional map types may be
registered at runtime.
Supported maps are:
LDAP <URI> [bindwhen=<when>] [version=<version>] [binddn=<DN>]
[credentials=<cred>]
The LDAP map expands a value by performing a simple LDAP
search. Its configuration is based on a mandatory URI,
whose attrs portion must contain exactly one attribute
(use entryDN to fetch the DN of an entry). If a multi-
valued attribute is used, only the first value is
considered.
The parameter bindwhen determines when the connection is
established. It can take the values now, later, and
everytime, respectively indicating that the connection
should be created at startup, when required, or any time
it is used. In the former two cases, the connection is
cached, while in the latter a fresh new one is used all
times. This is the default.
The parameters binddn and credentials represent the DN and
the password that is used to perform an authenticated
simple bind before performing the search operation; if not
given, an anonymous connection is used.
The parameter version can be 2 or 3 to indicate the
protocol version that must be used. The default is 3.
slapd <URI>
The slapd map expands a value by performing an internal
LDAP search. Its configuration is based on a mandatory
URI, which must begin with ldap:/// (i.e., it must be an
LDAP URI and it must not specify a host). As with the
LDAP map, the attrs portion must contain exactly one
attribute, and if a multi-valued attribute is used, only
the first value is considered.
