I met the same error, and the lastest openssh 8.1 is installed. But I assume sshpass doesn't pass the password correctly as the log. Would you have any suggestion? Thank you.

Hi,
I usually use expect, so tried sshpass and saw the same thing using AIX 7.5.2.1. In particular:
openssh.base.client/server 8.1.102.2101
openssl.base 1.0.2.2100
sshpass-1.06-2.ppc
.
Saw the same errors on AIX to AIX, AIX to Linux, but Linux to AIX okay
Turning on debugging on the endpoint
.
For vanila ssh providing password:
Apr 1 08:03:52 ibmpc3 auth|security:info sshd[20971840]: Accepted password for red from 192.168.138.141 port 37767 ssh2
Apr 1 08:03:52 ibmpc3 auth|security:info sshd[16253414]: Received disconnect from 192.168.138.141 port 37767:11: disconnected by user
Apr 1 08:03:52 ibmpc3 auth|security:info sshd[16253414]: Disconnected from user red 192.168.138.141 port 37767
Using sshpass with password (-p -e or -f flags all the same):
Apr 1 08:04:02 ibmpc3 auth|security:info sshd[20644186]: Failed password for red from 192.168.138.141 port 37772 ssh2

.
I will try next with wireshark to confirm if sshpass is actually sending something and update soon.
Cheers,

Hi,
Nothing stood out in wireshark..
.
I found running sshd in debug on a different port, vanila ssh showed
<snip>
debug1: kbdint_alloc: devices '' [preauth]^M
debug1: userauth-request for user red service ssh-connection method password [preauth]^M
debug1: attempt 3 failures 2 [preauth]^M
debug1: AIX/loginrestrictions returned 0 msg (none)^M
Accepted password for red from 192.168.138.141 port 32853 ssh2^M
debug1: AIX/loginsuccess: msg 4 unsuccessful login attempts since last login.
Last unsuccessful login: Thu Apr 8 04:20:09 CDT 2021 on ssh from 192.168.138.141
<\snip>
.
and with sshpass, similar up until
<snip>
debug1: kbdint_alloc: devices '' [preauth]^M
debug1: userauth-request for user red service ssh-connection method password [preauth]^M
debug1: attempt 3 failures 2 [preauth]^M
Failed none for red from 192.168.138.141 port 32860 ssh2^M
<\snip>
.
I downloaded version 1.09 from github and found the same error.
.
Sorry, will try a few other debugging options.
Cheers,
