I tested a Linux System and the password of the functional account has expired, how can configure TPAM to perform this action:
I got the following message: Password change required but no TTY available.
The password expired on the target Linux system, to correct this, you would need to un-expire or update the password age rules of the functional account on that target Linux system side. Please check with your Linux System Administrator for this part.
TPAM uses the functional account to connect to the target system and if the Test System fails then TPAM would not be able to perform any action on that target system.
