True enough.  But when I last looked at Notes (about 8 months
ago), I learned that Notes permits password guessing, adding a 30
second delay with each failed attempt, but no lockout and no logging.
Guessing the password using a dictionary attempt doesn't get you
into Notes because RSA is also used.  However, users typically
maintain the same password everywhere they login.  So using a Notes
server to guess a users password might provide access to other 
servers as well (for example, terminal servers with internal
network access, but lockouts on password guessing).

Your statement does not make sense. Who are you planning to guess the
password using a dictionary attack unless you also have the user's USER.ID
files? And if you have the USER.ID file and do guess the password you have
already broken in.
