Re: SSO solution in ports?

2009-07-17 Thread John Almberg
Well, after a week of looking, I think I am going to go with a CAS  
solution, rubycas-server and rubycas-client. This supports several  
methods of authentication, including SQL, ActiveDirectory, LDAP, and  
GoogleAccounts. SQL is probably good enough for my application at the  
moment, but the LDAP option might come in handy someday. And it  
integrates nicely with Rails apps, which is my target platform.


I looked at OpenID, which Rails also has good support for, but to my  
mind, it's just too complicated for the average user to use. I  
remember the first time I had to set one up, it was quite difficult  
to understand what it was they were looking for. I think it would  
scare away the average, non-technical, website user.


Thanks for the ideas!

Brgds: John

That won't really work as LDAP can't read a browser cookie or  
maintain session

information. LDAP is a good choice as storage backend.

Your best bet is probably to use an OpenID based solution, as  
support for this
sign on method is growing in web applications, so you lessen the  
chance of
having to maintain your custom glue into the application. The  
security/phpmyid
port is one implementation that allows you to run your own OpenID  
server.

Combine your SSO (LDAP mostly, Kerberos is a waking nightmare) with a
2FA/TFA (Second Factor Authentication) solution such as grid cards,
FOBs, or an OTP password list.

I recommend Entrust IdentityGuard.   Our pam_radius works fine with it,
and web application can run NSS functionality out of LDAP and PAM
functionality out of Entrust's SOAP-XML Authentication API.

SSO solution in ports?

2009-07-16 Thread John Almberg
I am trying to build a set of web applications that are accessed  
through a web portal that uses a Single Sign On (SSO) solution.  
Problem is, there are MANY competing SSO solutions. Since building  
the client side of the SSO system is more than enough for me, I was  
wondering if there are any SSO servers in ports that I can just  
install and use? A CAS solution would be the best, but I'll look at  
anything.


Any tips or ideas, much appreciated.

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.
