Goldstein Lyor commented on SSHD-549:
-------------------------------------
You are looking at 0.9.0 where according your own comment you should be looking
at the 0.14.0 version of
org/apache/sshd/server/auth/UserAuthKeyboardInteractive.java - FYI, there have
been some (major) changes between these versions - below is the 0.14.0 version
of the file. Also, make sure you add _new
MyUserAuthKeyboardInteractive.Factory()_ to the _userAuthFactories_

> Need to Change the password prompt

> Issue Type: Test
> Reporter: VENKATA DIGAVALLI
>
> Hi,
> I created the SSH server using Mina 2.0.7 libraries. During the login, the
> client application is looking for the text "Password:" and the SSH server
> handler seems to be sending back the prompt like "username@hostname
> passsword:".
> I believe this password prompt is picked from the sshd_config file on the
> linux server where this SSH server is running. Tried changing that config
> file, but still don't see any change in the password prompt text.
> This is causing a failure during login. Please let me know if there is any
> method in sshd libraries or any other solution I can use to override this
> password prompt during login.
> Thanks,
> Venkata Digavalli
