Since the ITS#4707 patch was not merged into 2.4 and is subject to additional modification
to handle a list of local addresses, perhaps it makes sense to leverage from what was done
in 2.3 and write a new patch for 2.4 (i.e. no merge)?
Regarding multiple local IP addresses, I can think of a scenario where the desired local
network interface has an IPv4 address and an IPv6 address, then the one which has the same
address family as the server's is chosen at the time of socket binding, but how to
match a client IP address with a server host address when there are multiple IPv4 and/or
IPv6 local addresses?

From what I can see, ldap_init_fd() only allows the setting of
UDP/TCP/IPC protocol type and server's URI.
Will the ITS#4707 patch
) be merged into 2.4?
And since this patch only handles one IP address, further change will be necessary to
support a list of IP addresses.

The notes say it was added for 2.4, but that apparently is incorrect.
"new API added in HEAD/RE24"
The notes say *a* new API was added to 2.4, not necessarily *this* one. And that is true,
we added ldap_init_fd() which lets the caller setup their socket any way they please.
