Kerberos (4 or 5) is synonymous with single sign on.  Kerberos support
is not as integrated with services as LDAP is.  I am almost the
paranoid security type and I don't know if SSO is really a "good idea"
(TM).  You obtain someone's *weak* password because they don't want
complexity, now the systems are wide open to them.  System Login/Email
are the two that bug me most.  "If I have your system login password,
I have your email password too.  Then anything else you hook into SSO
is also known"

So I battle myself every day with the mindset if SSO is truly a
worthwhile thing to look at, or if it should be at *most* two SSOs,
one for system login, one for "everything else"

Sorry to pull off on that tangent, but it seems nobody considers the
downside to SSO, and it's been nagging at me.
