[ale] Is there a limit on password length or characters for OUTBOUND sftp when receding a "password" prompt?

[Lightner, Jeffrey]

There may in fact be a password limit on local host that would prevent your test from working, but again I am doing the login to a remote host and it works when I go there from RHEL7 - just not when I do it from RHEL6 or RHEL5.   

That means the remote is in fact allowing the password - it is something with the local (RHEL6/RHEL5) not sending it properly somehow even though I have typed or cut and pasted it exactly the same way each time.   I know I'm typing or cut and pasting correctly because I am consistently getting the login to work when coming from RHEL7.

Sorry, brain's a bit slow. Tried on a CentOS 6 box, doing an sftp, ssh, and su to itself. All failed. Since the su failed that makes me think it's not ssh.

That is, I'm on a CentOS 6 box and tried ssh and sftp to the external IP, and then another account to su - to the long passworded account. All fail. When I changed the password back to something shorter it worked.

That suggests to me the issue is that something in the local sftp command on RHEL6 is not sending the password properly.   I suspect it is due to length i.e. sftp command doesn't allow for the 30+ character because it only expects to send something less (e.g. the 15/16 characters tantalizing mentioned in the Cisco bug) or it doesn't like the "-" that appears 4 times in the password.
