[Bug 1995157] [NEW] Permission Denied while using lates verions of Openssh client

[RaviModi]

Public bug reported:

Hi, 
I am having issues in connecting to OpenSSH Server. Error message is Permission Denied (publickey)

I am having following versions of OpenSSH Packages :

1) Windows 10 Client : OpenSSH_8.5p1, OpenSSL 1.1.1k 25 Mar 2021 (Installed via Git - older version)
1) Windows 11 Client : OpenSSH_9.0p1, OpenSSL 1.1.1q 5 Jul 2022    (Installed via Git 2.38.1 )
2) Windows 11 Client : OpenSSH_for_Windows_8.6p1  LibreSSL 3.4.3   (Installed via Windows 11 )
3) Ubuntu 14.04 Server  : OpenSSH_6.6.1p1   OpenSSL 1.0.1f
4) Ubuntu 22 Server :  OpenSSH_8.9p1 Ubuntu-3, OpenSSL 3.0.2 15 Mar 2022


I have recenty upgraded my WIndows Desktop & installed latest Windows 11 along with latest version of Git.
I am having several servers running Ubuntu 14.04 & connecting through git-bash. 
In my previous windows 10 version of OpenSSH I am able to successfully connect to Ubuntu 14.04 servers.  But after upgrading git to ver 9.0p1 I am unable to connect.  This latest version I can connect to Ubuntu 22 Servers successfully.

I am having single set of public & private keys which are properly
installed.

Old version of OpenSSH Client (8.5 / 8.6) can connect properly to both
servers Ubuntu 14.04 & 22

New version of OpenSSH Client 9.0p1 can connect only to Ubuntu 22
Servers.  On 14.04 server getting Permission Denied (publickey) message

Thanks
Ravi
