LDAP *ldap_open(const char *host, int port);
LDAP *ldap_init(const char *host, int port);
DESCRIPTION
The ldap_open() function initializes an LDAP session and
also opens a connection to an LDAP server before it returnsto 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 bespecified 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. Theldap_open() and ldap_init() functions attempt connections
with LDAP hosts in the order listed and return the first successful connection.PARAMETERS
These functions support the following parameters. host The hostname, IPv4 or IPv6 address of the host thatruns 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 constantLDAP_PORT to obtain the default LDAP port of 389. If
a host includes a port number, the default parameter is ignored.RETURN VALUES
The ldap_open() and ldap_init() functions return a handle to

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 orwritten 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.EXAMPLES
Example 1 Specifying IPv4 and IPv6 Addresses LDAP sessions can be initialized with hostnames, IPv4 orIPv6 addresses, such as those shown in the following exam-
ples.ldap_init("hosta:636 hostb", 389)
ldap_init("192.168.82.110:389", 389)
ldap_init("[fec0::114:a00:20ff:ab3d:83ed]", 389)
