RE: Single Sign-On with Accumulo
This model of authentication pass-through is used in plenty of places within
DoD. All CAC-enabled DoD webmail uses this via Kerberos delegation in active
directory for example.

Just to clarify, the suggestions is that after a user authenticates to a web
service, that web service identifies the authorization of the user and the
web service passes credientials of the appropriate level to Accumulo.
Correct? The web service acts like a broker of authorization?

 

There are many potential uses for a cell based security database.  One use
is in securing DoD data of different security classifications (hence part of
the reason for NSA involvement in the Accumulo project).  However, I don't
think the above method of user authorization would pass DoD accredidation.
At least, it would be very difficult to get accredited.  Has the web service
authentication broker method ever been used in a system that has been
accredited?

 

When will Accumulo 1.5 be released?

 

Thanks,

Thorton

Accumulo 1.4 handles all of it's security internally, so you can't rely on
an external service for managing the user space. However, you can have a web
service which handles passing accumulo credentials down into the system so
you don't have to worry about the web service doing anything too elaborate.

Accumulo 1.5 is slated to have a pluggable security structure, which will
support a variety of SSO mechanisms.

Are there single sign-on options for Accumulo (like SAML or CAS or something
else)?  

I'm interested in using Accumulo's cell-level security behind a web service.
The web service would require authentication that I would like to pass on to
Accumulo.  This would allow Accumulo to handle the filtering of requests
results based on the users authorization, instead of the web service having
to do it.  Is this possible?

 

Thanks,

Thorton
