Good that it can be "reproduced" at least in this form.

If I change args to "ldapsearch" "-W" (and prompt, accordingly), then

- with process-connection-type t, the test exits normally, and buffer
  contains the same text as for you:

  Enter LDAP Password: 
  ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)

  Process my-process exited abnormally with code 255

- with process-connection-type nil, the test hangs, and when I quit, the
  buffer contains:

  Process my-process stopped (tty output): 22

I see that /usr/bin/read is not the best thing to test with, because I
don't know exactly what it's doing.

My ldapsearch (2.4.28) is from macOS - they don't update it frequently.

I'll try a later version.  Other than that, I don't know what to do for
now :-(
