ldap_open, ldap_init - initialize an LDAP session
cc [ flag... ] file... -lldap [ library... ] #include <lber.h> #include <ldap.h> LDAP *ldap_open(const char *host, int port); LDAP *ldap_init(const char *host, int port);
The ldap_open() function initializes an LDAP session and also opens a connection to an LDAP server before it returns to the caller. Unlike ldap_open(), ldap_init() does not open a connection to the LDAP server until an operation, such as a search request, is performed. The ldap_open() function is deprecated and should no longer be used. Call ldap_init() instead. A list of LDAP hostnames or an IPv4 or IPv6 address can be specified with the ldap_open() and ldap_init() functions. The hostname can include a port number, separated from the hostname by a colon (:). A port number included as part of the hostname takes precedence over the port parameter. The ldap_open() and ldap_init() functions attempt connections with LDAP hosts in the order listed and return the first suc- cessful connection.
These functions support the following parameters. host The hostname, IPv4 or IPv6 address of the host that runs the LDAP server. A space-separated list of hostnames can also be used for this parameter. port TCP port number of a connection. Supply the constant LDAP_PORT to obtain the default LDAP port of 389. If a host includes a port number, the default parameter is ignored.
The ldap_open() and ldap_init() functions return a handle to an LDAP session that contains a pointer to an opaque structure. The structure must be passed to subsequent calls for the session. If a session cannot be initialized, the functions return NULL and errno should be set appropriately. Various aspects of this opaque structure can be read or written to control the session-wide parameters. Use the ldap_get_option(3LDAP) to access the current option values and the ldap_set_option(3LDAP) to set values for these options.
Example 1: Specifying IPv4 and IPv6 Addresses LDAP sessions can be initialized with hostnames, IPv4 or IPv6 addresses, such as those shown in the following examples. ldap_init("hosta:636 hostb", 389) ldap_init("", 389) ldap_init("[fec0::114:a00:20ff:ab3d:83ed]", 389)
