Password echo to console under Cygwin MinTTY.(Windows)

[rctrh]

Under a Cygwin installation on Windows (the terminal window is Mintty, running bash by default), the password is echoed. There is a message about fixing your stdin.

It seems like something isn't quite working right. The terminal is functional enough that other programs like ssh (openssh) for example, doesn't have a problem changing the terminal settings to disable echo.

I'm not sure where to start debugging this. The cygwin environment includes stty.

I have a vague recollection of this working properly in the past, possibly in the 1.0 time frame.

Can you include the plugin version used and some steps for setting this environment on Windows?

[rctrh]

Registration version 1.0.1, Cygwin MinTTY 1.1.3, Bash 4.1.10, Windows 7/64 bit.
Box: rhel-cdk-kubernetes-7.2-6.x86_64.vagrant-virtualbox.box (cdkv2 beta 3)

$ vagrant plugin list
vagrant-adbinfo (0.0.5)
  - Version Constraint: 0.0.5
vagrant-registration (1.0.1)
vagrant-share (1.1.4, system)

$ vagrant version
Installed Version: 1.7.4
Latest Version: 1.7.4

You're running an up-to-date version of Vagrant!

Here's the output from vagrant up:

Note: I didn't hit enter twice, it printed the password prompt, then the error about stdin, then the password prompt again.

Definitely something to look at. @pvalena can hopefully try to run it on Windows now or soon enough.

no problem when running vagrant up under cmd.exe

The problem is with Cygwin. I seem to recall, this worked fine in the CDK 1.0 timeframe.

Unless Cygwin isn't considered a valid environment, this should be considered a bug.
