.SH NAME
|
|
ldap - OpenLDAP Lightweight Directory Access Protocol API
|
|
.SH SYNOPSIS
|
|
.nf
|
|
.ft B
|
|
#include <ldap.h>
|
|
.ft
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.LP
|
|
The Lightweight Directory Access Protocol provides access to
|
|
X.500 directory services. The services may be stand\-alone
|
|
part of a distributed directory service. This API supports
|
|
LDAP over TCP, LDAP over SSL, and LDAP over IPC (UNIX domain
|
|
sockets).
|
|
.LP
|
|
The OpenLDAP LDAP package includes a stand-alone server in
|
|
.BR slapd (8),
|
|
various LDAP clients, and an LDAP client library used to provide
|
|
programmatic access to the LDAP protocol. This man page gives an
|
|
overview of the LDAP library routines.
|
|
.LP
|
|
Both synchronous and asynchronous APIs are provided. Also included are
|
|
various routines to parse the results returned from these routines.
|
|
These routines are found in the \-lldap library.
|
|
.LP
|
|
The basic interaction is as follows. A session handle associated
|
|
with created using
|
|
.BR ldap_init (3).
|
|
The underlying session is established upon first use which is
|
|
commonly an LDAP bind operation. The LDAP bind operation is
|
|
performed by calling one of
|
|
.BR ldap_sasl_bind (3)
|
|
and friends. Next, other operations are performed
|
|
by calling one of the synchronous or asynchronous routines (e.g.,
|
|
.BR ldap_search_ext_s (3)
|
|
or
|
|
.BR ldap_search_ext (3)
|
|
followed by
|
|
.BR ldap_result (3)).
|
|
Results returned from these routines are interpreted by calling the
|
|
LDAP parsing routines such as
|
|
.BR ldap_parse_result (3).
|
|
The LDAP association and underlying connection is terminated by calling
|
|
.BR ldap_unbind_ext (3).
|
|
Errors can be interpreted by calling
|
|
.BR ldap_err2string (3).
|
|
.SH SEARCH FILTERS
|
|
Search filters to be passed to the ldap search routines can be
|
|
constructed by hand, or by calling the
|
|
.BR ldap_getfilter (3)
|
|
routines, which use the
|
|
.BR ldapgetfilter.conf (5)
|
|
file to turn a string (presumably that a user has typed) into a series
|
|
of search filters.
|
|
.SH DISPLAYING RESULTS
|
|
Results obtained from the ldap search routines can be output by hand,
|
|
by calling
|
|
.BR ldap_first_entry (3)
|
|
and
|
|
.BR ldap_next_entry (3)
|
|
to step through
|
|
the entries returned,
|
|
.BR ldap_first_attribute (3)
|
|
and
|
|
.BR ldap_next_attribute (3)
|
|
to step through an entry's attributes, and
|
|
.BR ldap_get_values (3)
|
|
to retrieve a given attribute's value. Attribute values
|
|
may or may not be displayable.
|
|
.LP
|
|
Alternatively, the entry can be output automatically by calling
|
|
the
|
|
.BR ldap_entry2text (3),
|
|
.BR ldap_entry2text_search (3),
|
|
.BR ldap_entry2html (3),
|
|
or
|
|
.BR ldap_entry2html_search (3)
|
|
routines. These routines look up the object
|
|
class of the entry they are passed in the
|
|
.BR ldaptemplates.conf (5)
|
|
file to decide which attributes to display and how to display them.
|
|
Output is handled via a routine passed in as a parameter.
|
|
.SH UNIFORM RESOURCE LOCATORS (URLS)
|
|
The
|
|
.BR ldap_url (3)
|
|
routines can be used test a URL to see if it is an LDAP URL, to parse LDAP
|
|
URLs into their component pieces, and to initiate searches directly using
|
|
an LDAP URL.
|
|
.SH USER FRIENDLY NAMING
|
|
The
|
|
.BR ldap_ufn (3)
|
|
routines implement a user friendly naming
|
|
scheme via LDAP. This scheme allows you to look up entries
|
|
using fuzzy, untyped names like "john smith, example corp, ca, us".
|
|
.SH CACHING
|
|
The
|
|
.BR ldap_cache (3)
|
|
routines implement a local client caching scheme,
|
|
providing a substantial performance increase for repeated queries.
|
|
.SH UTILITY ROUTINES
|
|
Also provided are various utility routines. The
|
|
.BR ldap_sort (3)
|
|
routines are used to sort the entries and values returned via
|
|
the ldap search routines. The
|
|
.BR ldap_friendly (3)
|
|
routines are
|
|
used to map from short two letter country codes (or other strings)
|
|
to longer "friendlier" names.
|
|
.SH BER LIBRARY
|
|
Also included in the distribution is a set of lightweight Basic
|
|
Encoding Rules routines. These routines are used by the LDAP library
|
|
routines to encode and decode LDAP protocol elements using the
|
|
(slightly simplified) Basic Encoding Rules defined by LDAP. They are
|
|
not normally used directly by an LDAP application program excepting
|
|
in the handling of controls and extended operations. The
|
|
routines provide a printf and scanf-like interface, as well as
|
|
lower-level access. These routines are found in the -llber
|
|
library.
