LDAP_OPT_SOCKET_BIND_ADDRESSES
0x44

Sets or retrieves a pointer to a TCHAR string containing a list of space-se=
parated addresses to be used by socket bind. For a multihomed machine, use =
this option to set a particular network interface address to be used for so=
cket bind. Socket bind will be performed before socket connect for the serv=
er address. See socket bind for more details.

You should provide both IPv4 and IPv6 local addresses, if available, becaus=
e both IPv4 and IPv6 server addresses can be used for socket connect. Socke=
t bind will fail if there is an address family mismatch. On the Domain Cont=
roller, for the default Server (HostName=3DNULL), loopback addresses will b=
e used for socket connect. Set loopback addresses (for both IPv4 and IPv6) =
for this option to work.

This option can only be set before a connection is established. That is, ju=
st after ldap_init.

-------------------------------
I am not sure what "a list of space-separated addresses" exactly means. Per=
haps one IPv4 IP address and one IPv6 address if both are available. My use=
 case is either a local IPv4 or IPv6 address.
