A username that is greater than 8 characters is unable to login to hpux system prior to 11iv3 (11.31) via SSH, telnet, login, or ftp
The PAM debug or sshd debug files show a similiar error to the below:
sshd: error: PAM: No account present for user.
sshd: fatal: PAM: pam_setcred(): No account present for user
3rd Party character length issue. HP-UX 11.23 has an 8 character limit for the username. QAS does not adhere to the limits; however, underlining PAM authentication libraries and HP-UX utilities do.
Use a "user-override" file to override the usernames to less than 8 characters.
Would allow the email@example.com user to log on with the username shortnam instead.
Use login names < 9 characters
Upgrade to HPUX 11.31 which allows login names up to 255 characters
