I've got a chance to write (and test) the code to add API support for
socket binding addresses.
Should I send the code diff to this openldap-devel email list for review?
How to submit a patch request?

Subject: ITS#8654 - Option for LDAP client to bind to a local address
In reference to the enhancement request ITS#865, please comment on the
following to add support for binding a local IP address to client socket.
This is just an outline of changes for one local address. I am not sure
whether a list of local addresses is necessary. If it is, then a new
function, similarly to ldap_url_parsehosts, may be written to parse the
list of local addresses and store them into a linked list. In my use
case, only one IPv4 or IPv6 local address is used for binding.
- Modify ldap.h and ldap_set_option to handle the new option
LDAP_OPT_LOCAL_ADDRESS. Should it be named LDAP_OPT_CLIENT_ADDRESS,
- Modify struct ldapoptions in ldap-int.h to add element "char
*ldo_local_address" to hold client local address when
ldap_set_option(LDAP_OPT_LOCAL_ADDRESS...) is executed. This can char
pointer can point to an IPv4 address or IPv6 address.
- ldap_connect_to_host() in os-ip.c
After the connection socket is created (ldap_int_socket) and before it
is connected (ldap_pvt_connect), extract the local IP address. If local
address family (AF_INET/ AF_INET6) matches the one of the host, bind
socket to the local address.
