See COPYRIGHT/LICENSE. +.SH NAME +ldap \- OpenLDAP Lightweight Directory Access Protocol API +.SH LIBRARY +OpenLDAP LDAP (libldap, \-lldap) +.SH SYNOPSIS +.nf +.ft B +#include <ldap.h> +.ft +.fi +.SH DESCRIPTION +.LP +The Lightweight Directory Access Protocol (LDAP) (RFC 4510) provides +access to X.500 directory services. These services may be stand\-alone +or part of a distributed directory service. This client API supports +LDAP over TCP (RFC 4511), LDAP over TLS/SSL, and LDAP over IPC (UNIX +domain sockets). This API supports SASL (RFC 4513) and Start TLS +(RFC 4513) as well as a number of protocol extensions. This API is +loosely based upon IETF/LDAPEXT C LDAP API draft specification, a (orphaned) +work in progress. +.LP +The OpenLDAP Software 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 is +created using +.BR ldap_initialize (3) +and set the protocol version to 3 by calling +.BR ldap_set_option (3). +The underlying session is established first operation is +issued. This would generally be a Start TLS or Bind operation, +or a Search operation to read attributes of the Root DSE. +A Start TLS operation is performed by calling +.BR ldap_start_tls_s (3). +A LDAP bind operation is performed by calling +.BR ldap_sasl_bind (3) +or one of its friends. +A Search operation is performed by calling ldap_search_ext_s(3) +or one of its friends. + +Subsequently, additional operations are performed +by calling one of the synchronous or asynchronous routines (e.g., +.BR ldap_compare_ext_s (3) +or +.BR ldap_compare_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 LDAP versions +This library supports version 3 of the Lightweight Directory Access +Protocol (LDAPv3) as defined in RFC 4510. It also supports a variant +of version 2 of LDAP as defined by U-Mich LDAP and, to some degree, +RFC 1777. Version 2 (all variants) are considered obsolete. +Version 3 should be used instead. +.LP +For backwards compatibility reasons, the library defaults to version 2. +Hence, all new applications (and all actively maintained applications) +should use +.BR ldap_set_option (3) +to select version 3. The library manual pages assume version 3 +has been selected. +.SH INPUT and OUTPUT PARAMETERS +All character string input/output is expected to be/is UTF-8 +encoded Unicode (version 3.2). +.LP +Distinguished names (DN) (and relative distinguished names (RDN) to +be passed to the LDAP routines should conform to RFC 4514 UTF-8 +string representation. +.LP +Search filters to be passed to the search routines are to be +constructed by hand and should conform to RFC 4515 UTF-8 +string representation. +.LP +LDAP URLs to be passed to routines are expected to conform +to RFC 4516 format. The +.BR ldap_url (3) +routines can be used to work with LDAP URLs. +.LP +LDAP controls to be passed to routines can be manipulated using the +.BR ldap_controls (3) +routines. +.SH DISPLAYING RESULTS +Results obtained from the 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 values. Attribute values +may or may not be displayable. +.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. +.SH DEPRECATED INTERFACES +A number of interfaces are now considered deprecated. For instance, +ldap_add(3) is deprecated in favor of ldap_add_ext(3). +.so Deprecated +.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 except +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 discussed in +.BR lber\-decode (3), +.BR lber\-encode (3), +.BR lber\-memory (3), +and +.BR lber\-types (3). +.SH INDEX +.TP 20 +.SM ldap_initialize(3) +initialize the LDAP library without opening a connection to a server +.TP +.SM ldap_result(3) +wait for the result from an asynchronous operation +.TP +.SM ldap_abandon_ext(3) +abandon (abort) an asynchronous operation +.TP +.SM ldap_add_ext(3) +asynchronously add an entry +.TP +.SM ldap_add_ext_s(3) +synchronously add an entry +.TP +.SM ldap_sasl_bind(3) +asynchronously bind to the directory +.TP +.SM ldap_sasl_bind_s(3) +synchronously bind to the directory +.TP +.SM ldap_unbind_ext(3) +synchronously unbind from the LDAP server and close the connection +.TP +.SM ldap_unbind(3) and ldap_unbind_s(3) are +equivalent to +.BR ldap_unbind_ext (3) +.TP +.SM ldap_memfree(3) +dispose of memory allocated by LDAP routines. +.TP +.SM ldap_compare_ext(3) +asynchronously compare to a directory entry +.TP +.SM ldap_compare_ext_s(3) +synchronously compare to a directory entry +.TP +.SM ldap_delete_ext(3) +asynchronously delete an entry +.TP +.SM ldap_delete_ext_s(3) +synchronously delete an entry +.TP +.SM ld_errno(3) +LDAP error indication +.TP +.SM ldap_errlist(3) +list of LDAP errors and their meanings +.TP +.SM ldap_err2string(3) +convert LDAP error indication to a string +.TP +.SM ldap_extended_operation(3) +asynchronously perform an arbitrary extended operation +.TP +.SM ldap_extended_operation_s(3) +synchronously perform an arbitrary extended operation +.TP +.SM ldap_first_attribute(3) +return first attribute name in an entry +.TP +.SM ldap_next_attribute(3) +return next attribute name in an entry +.TP +.SM ldap_first_entry(3) +return first entry in a chain of search results +.TP +.SM ldap_next_entry(3) +return next entry in a chain of search results +.TP +.SM ldap_count_entries(3) +return number of entries in a search result +.TP +.SM ldap_get_dn(3) +extract the DN from an entry +.TP +.SM ldap_get_values_len(3) +return an attribute's values with lengths +.TP +.SM ldap_value_free_len(3) +free memory allocated by ldap_get_values_len(3) +.TP +.SM ldap_count_values_len(3) +return number of values +.TP +.SM ldap_modify_ext(3) +asynchronously modify an entry +.TP +.SM ldap_modify_ext_s(3) +synchronously modify an entry +.TP +.SM ldap_mods_free(3) +free array of pointers to mod structures used by ldap_modify_ext(3) +.TP +.SM ldap_rename(3) +asynchronously rename an entry +.TP +.SM ldap_rename_s(3) +synchronously rename an entry +.TP +.SM ldap_msgfree(3) +free results allocated by ldap_result(3) +.TP +.SM ldap_msgtype(3) +return the message type of a message from ldap_result(3) +.TP +.SM ldap_msgid(3) +return the message id of a message from ldap_result(3) +.TP +.SM ldap_search_ext(3) +asynchronously search the directory +.TP +.SM ldap_search_ext_s(3) +synchronously search the directory +.TP +.SM ldap_is_ldap_url(3) +check a URL string to see if it is an LDAP URL +.TP +.SM ldap_url_parse(3) +break up an LDAP URL string into its components +.TP +.SM ldap_sort_entries(3) +sort a list of search results +.TP +.SM ldap_sort_values(3) +sort a list of attribute values +.TP +.SM ldap_sort_strcasecmp(3) +case insensitive string comparison +.SH SEE ALSO +.BR ldap.conf (5), +.BR slapd (8), +.BR draft-ietf-ldapext-ldap-c-api-xx.txt \ <http://www.ietf.org> +.SH ACKNOWLEDGEMENTS +.so ../Project +.LP +These API manual pages are loosely based upon descriptions provided +in the IETF/LDAPEXT C LDAP API Internet Draft, a (orphaned) work +in progress. + |
