Request to have LTPAToken does not contain the user's authenticated name to prevent brute force attack.

As the technote below mentions, LTPAToken cookie contains the user's authenticated name encoded base64.
That is, the attacker could crack the password by using a brute force attack.

How secure is the Domino LtpaToken cookie?

Internet password lockout function; Server > Configurations > Security >  Enforce Internet Password Lockout, prevents brute force attack, though, it would be much more secure if LTPAtoken cookie does not contain the user's authenticated name.

    Please note that the LTPAToken format was created and is owned by WebSphere, not by Domino.
