Enforcing password rules is more important when the user changes their
own password.  If you look at the changePassword() and
changePasswordByAdmin() on the AEPearDBProvider you'll notice we verify
the strength of the password against our configured rules.  If you can
at least agree to that much, I don't think it is a stretch to say we may
as well enforce the rules on passwords generated by our system.

Use of regex is fine, I personally don't like it because it is hard to
read and this code probably won't get hammered too much but the
performance gain is duly noted and I'm flexible.

The hard part is deciding how much Auth_Enterprise should do versus the
application.  You could very easily implement that at the application
level.  If you notice, right now I don't even have different
registration methods because I think I'd like to see a good discussion
by us all on whether or not we should add this.  I think the answer is
yes we should include this stuff but if we do so it will make the
administration and support more complicated for end users.  For now all
I did was implement the createAccount() method and figured we'd wrap all
the bells and whistles in after we make some final decisions.  A big factor
in making this decision is whether or not we require email capabilities on
the Auth_Enterprise server especially in the chance the users is running
the server remote from the application.

Just keep in mind that Geeklog 2, from my view point, is less to do with
the hobbyists and more to do with the attractiveness for businesses and
organizations.  Granted, our current user base is important to us and I
can't highlight that enough but the days of my writing software with no
sort of compensation is coming to an end.  Obviously this is only my
personal take and it may come off a bit selfish but GL2 will basically
end up deciding how involved I stay.

Bottom line is when installing Geeklog 2, Auth_Enterprise should install
itself seamlessly and with little to no hassle so, from that view,
nothing should change.  My plans to support this are we will include the
Auth_Enterprise table structures into the Geeklog2 database and default
it to the AEPearDBProvider for all account management.  Those who want
LDAP or some other configuration will simply have more work (albeit
fairly trivial work).

Implementing SSO is actually pretty easy.  All you would have to do is
add some session tables to the database and, using PHP sessions, we
would serialize the AEServiceUser object there.  Using SSO would require
a single login page for all applications so that an SSO token can be
added to the cookies and then a few new methods to the API for verifying
SSO tokens.

I'm open to suggestions.
