What is the best (and simple) way to implement security in a Phoebus solution?

[Oscar Ibañez via Tech-talk <tech-talk@aps.anl.gov>]

Hi everybody again,

I have a new doubt about Phoebus. Now it is about security.

Is there any recomendable solution to implement username authentication 
in Phoebus? I mean, some kind of solution to save critical information 
(password hash?) that, then, it will be used to authenticate an user. I 
have been reading some information about it, but always in the CSS BOY 
context. The explanations that I have found some... well, over the top. 
I need something simpler. I don't need Kerberos or something like that.
Best regards.
