PAM (Privileged account Management) to maintain the system account(used for integration or administration - non user based AD accounts ) & there password.
This help in implementing password expiry policy for system accounts, PAM automatically changes and maintains passwords for these accounts. Also, PAM monitors all activity done by these accounts.
However, at present TDV does not allow to change stored passwords to PAM when it is expired.
So, Expectation is that TDV should allow PAM to modify password periodically.
PAM module is the custom code provide by the implementor of the module. Any information used by the module is the responsibility of the developer & we would like to understand what is required of us here.
