Anyone facing the same issue like us, PAN OS 10.2.3-h4, SSH CLI session got disconnected after we login as user AD auth (User Authentication Successful). Is it bug not yet reported?

Hello Yoekleng,
There is a limitation in 10.2 where for security reasons centos have disallowed usernames with numbers only and PANOS depends on that Centos functionality to store usernames for authorization purposes. -->> "Fully numeric usernames and usernames . or .. are also disallowed" is the CentOS behavior change by https://www.webconn.tech/kb/are-all-numeric-usernames-allowed-in-almalinux-8:
Usernames may contain only lower and upper case letters, digits, underscores, or dashes. They can end with a dollar sign. Dashes are not allowed at the beginning of the username. Fully numeric usernames and usernames. or .. are also disallowed. It is not recommended to use usernames beginning with. character as their home directories will be hidden in the ls output. In regular expression terms: [a-zA-Z0-9_.][a-zA-Z0-9_.-]*[$]? -->> There are good reasons to enforce it:
https://unix.stackexchange.com/questions/287077/why-cant-linux-usernames-begin-with-numbers
So this behavior is per design and functionality. --
>>WORKAROUND: We can add a symbol along with letters to the numbers the Admin Username then works. For example, 12345676890_A

Hi Bharath,
You can try and test at your end. However, It is not recommended to downgrade since the latest release fixed a bug and vulnerabilities.
Best Regards,
Yoekleng.
