<BODY>
<P><FONT SIZE=2>I think the three heads represent the client, server and KDC in Kerberos.</FONT>

<P><FONT SIZE=2>And not to forget are actually 4 A's for Kerberos: Authentication, Authorization, Auditing/Acounting, Administration.</FONT>

<P><FONT SIZE=2>Mark is certainly correct that AAA (although I think A tended to stand</FONT>

<BR><FONT SIZE=2>to have some value if we don't want to change the icon to a head and</FONT>
<BR><FONT SIZE=2>two bloody stumps. Unfortunately I cannot remember where I heard the</FONT>
<BR><FONT SIZE=2>second interpretation; certainly not here at MIT.</FONT>
