Description
A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the system but does not want to log out because of the temporary nature of the absence. Once invoked, the session lock shall remain in place until the user re-authenticates. No other system activity aside from re-authentication can unlock the system. Permanent finding - Lockdown mode (required) limits access via the vpxuser proxy (password is 32 chars, not configurable, and changed every 30 days "or" sooner when/if a new host is configured/controlled by the vCenter Server). There is No LOCK function for the Shell or SSH.
