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

[Raj Wurttemberg]

Hey Jeff,

Silly thought...  Could there be a max password length set in PAM or
login.defs?  Or maybe 'pam_cracklib.so' can't handle more than 32
characters?

Tried on what?

As noted the password actually works on the remote system if I do sftp from
a RHEL7 server to the remote.    So whatever they're running on the remote
has no problem with a password that long.  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.   

NB:  The remote is NOT Cisco - I only mention Cisco because it was the only
thing I saw that suggested a length limit in all my web searches.

Hmm...sorry. I missed that.

Well, I just tried a 32 character alphanumeric password for both ssh, sftp,
and su. All failed. So it looks like password is the issue, not ssh.
