SSHFS no write permissions - Yosemite

[Jack S.]

I'm unable to create or delete any files on a SSHFS volume mounted on a Yosemite client.  I've tried it on SSHFS 2.4 with OSXFUSE 2.7.1 as well as SSHFS 2.5.0 with OSXFUSE 2.7.2.  I can mount the remote file system without a problem, but it won't let me write to it.  I'm able to write to it without issues when I mount it on other systems (Linux & FreeBSD) vis SSHFS.  I'm using the same command and credentials on all the systems.
When I enable SSHFS debugging on the Yosemite machine, I see the following errors:

debug1: Authentication succeeded (keyboard-interactive).

(complete debug log attached)

Is it a bug in FUSEFS or am I doing something wrong?

I just mounted the same remote fs on a system running Mavericks - using OSXFUSE 2.7.2 and SSHFS 2.5.0 and I'm having the same issue as the Yosemite computer.  What gives?  Linux and FreeBSD are able to write to the same remote fs, using the same credentials just fine.

You can use the free version of WingFS for ssh (sftp) mounts. It can not only mount ssh(sftp) but many other services.
