Per my own testing and posts in this forum, the root account becomes locked after 4 failed attempts.
/sbin/pam_tally2 -r -u root
We have automatic security scanning systems in place which periodically test common passwords against all of our systems, to ensure that nothing is using a weak or default password.
This effectively means that we have to use this onerous password reset process every time that we want to login to the root account, since it'll have been automatically locked out.
This does not happen with ESXi, vCenter, vROPs, LogInsight, etc. appliances. Either the account does not get locked out, or is automatically unlocked after some time interval.
Please update the Skyline appliance to match the behavior of VMware's other appliances, or let me know if I'm missing something.
Welcome to communities !!!
Thank you for the feedback. We will discuss with engineering regarding the root password concern and get back to you.
