[Issue 9839] Undocumented behavior of ldap_url_parse() when port is 0 in URL string

Port=0 is meaningless for clients, so why would anyone ever run into this?

In #9596 it's done to allow slapd to listen on a dynamically assigned port. There is no use case for it anywhere else. It's also questionable whether the change for #9596 is actually appropriate.

+1, I also think listening on a dynamically assigned port is almost useless for the slapd daemon.

Btw, invalid ports numbers like -1, 2147483648 (INT32_MAX + 1) can get parsed successfully by ldap_url_parse(). Do you think this is a bug? If so, I will submit patch for it.
