System and method for preventing well behaving clients from causing account lockouts in a group

An information handling system, comprising:

• a processor subsystem having access to a first memory;
• a management controller comprising a secondary processor having access to a second memory, the second memory including an embedded storage partition and the second memory storing instructions executable by the secondary processor to:
• send a message to a member, the message having a first timestamp associated with a message received from the member prior to sending the message;
• increase an authentication failure count;
• receive a first key-exchange message from the member, the first key-exchange message having a value computed by the member based on a group passcode shared with the member and a second timestamp;
• evaluate the second timestamp based on at least one of:
• a default value, the authentication failure count, or a timestamp associated with the group passcode;
• and
• determine whether to ignore the first key-exchange message based on the evaluation of the second timestamp.

A management controller for an information handling system having a primary processor and a primary memory, the management controller comprising a secondary processor having access to a secondary memory, the secondary memory including an embedded storage partition and the secondary memory storing instructions executable by the secondary processor to:

• send a message to a member, the message having a first timestamp associated with a message received from the member prior to sending the message;
• increase an authentication failure count;
• receive a first key-exchange message from the member, the first key-exchange message having a value computed by the member based on a group passcode shared with the member and a second timestamp;
• evaluate the second timestamp based on at least one of:
• a default value, the authentication failure count, or a timestamp associated with the group passcode;
