Unlike \fBldap_open()\fR, \fBldap_init()\fR does not open a connection to the LDAP server until an operation, such as a search request, is performed. .sp .LP The \fBldap_open()\fR function is deprecated and should no longer be used. Call \fBldap_init()\fR instead. .sp .LP A list of LDAP hostnames or an IPv4 or IPv6 address can be specified with the \fBldap_open()\fR and \fBldap_init()\fR functions. The hostname can include a port number, separated from the hostname by a colon (\fB:\fR). A port number included as part of the hostname takes precedence over the \fIport\fR parameter. The \fBldap_open()\fR and \fBldap_init()\fR functions attempt connections with LDAP hosts in the order listed and return the first successful connection. .SH PARAMETERS .sp .LP These functions support the following parameters. .sp .ne 2 .mk .na \fB\fIhost\fR\fR .ad .RS 8n .rt 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. .RE .sp .ne 2 .mk .na \fB\fIport\fR\fR .ad .RS 8n .rt TCP port number of a connection. Supply the constant \fBLDAP_PORT\fR to obtain the default LDAP port of 389. If a host includes a port number, the default parameter is ignored. .RE .SH RETURN VALUES .sp .LP The \fBldap_open()\fR and \fBldap_init()\fR 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 \fINULL\fR and \fBerrno\fR should be set appropriately. .sp .LP Various aspects of this opaque structure can be read or written to control the session-wide parameters. Use the \fBldap_get_option\fR(3LDAP) to access the current option values and the \fBldap_set_option\fR(3LDAP) to set values for these options. .SH EXAMPLES .LP \fBExample 1 \fRSpecifying IPv4 and IPv6 Addresses .sp .LP LDAP sessions can be initialized with hostnames, IPv4 or IPv6 addresses, such as those shown in the following examples. .sp .in +2 .nf ldap_init("hosta:636 hostb", 389) ldap_init("192.168.82.110:389", 389) ldap_init("[fec0::114:a00:20ff:ab3d:83ed]", 389) .fi .in -2 .sp .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for descriptions of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
