All work should be done against OpenLDAP master rather than a release branch
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?
Curious, does telnet -b handle this currently?

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 (ftp://ftp.openldap.org/incoming/openldap-2.3.27-bindaddr.patch.txt) 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.

Wasn't this patch integrated into OpenLDAP 2.3.X? I couldn't see it in the 2.4.44 code base.
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.

How does one check out code from the OpenLDAP master branch?
I don't know the telnet code but its manual about -b option refers to 'an' aliased address or to 'the' address, not multiple IPV4 or IPv6 addresses.
-b hostalias Uses bind(2) on the local socket to bind it to an aliased address (see ifconfig(8) and the ''alias'' specifier) or to the address of another interface than the one naturally chosen by connect(2). This can be useful when connecting to services which use IP addresses for authentication and reconfiguration of the server is undesirable (or impossible).
