.SH DESCRIPTION
.sp
.LP
The \fBcldap_open()\fR function is called to prepare for connectionless LDAP
communication (over \fBudp\fR(4P)). It allocates an LDAP structure which is
passed to future search requests.
.sp
.LP
If the default IANA-assigned port of 389 is desired,  \fBLDAP_PORT\fR should be
specified for \fIport\fR. \fIhost\fR can contain a space-separated list of
hosts or addresses to try. \fBcldap_open()\fR returns a pointer to an LDAP
structure, which should be passed to subsequent calls to
\fBcldap_search_s\fR(3LDAP), \fBcldap_setretryinfo\fR(3LDAP), and
\fBcldap_close\fR(3LDAP). Certain fields in the LDAP structure can be set to
indicate size limit, time limit, and how aliases are handled during operations.
See \fBldap_open\fR(3LDAP) and  \fB<ldap.h>\fR for more details.
.SH ERRORS
.sp
.LP
If an error occurs, \fBcldap_open()\fR will return  \fINULL\fR and  \fBerrno\fR
will be set appropriately.
