[amfphp] Authentication/authorization system using Flex 2 and AMFPHP 1.9b2

[<joa...@we...>]

Hi,

I need to create an authentication/authorization system with Flex and 
PHP using AMFPHP 1.9 beta 2.
I have a login form, and from the moment the user logs in, it's access 
to some remote service is defined by the role(s) of the user.
I have made something very similar to this using AMFPHP 1.2 and Flash 8 
some months ago, thanks to the method table that allowed us to define 
roles to the services on a very easy and straightforward way. But now on 
AMFPHP 1.9b2 the method table is deprecated, so i do not see how to 
achieve this...
Also, i've tried using setCredentials on Flex 2 and AMFPHP 1.9b2, which 
results on an AMFPHP exception.

So:
1- Can you give me advices on how to create an authentication system 
using Flex 2 and AMFPHP 1.9b2 ? Does .setCredentials works?
2- Can you give me advices on how to create an authorization system 
using Flex 2 and AMFPHP 1.9b2 ?

It's not the first time I make this question, but I definitely need to 
solve this on the current project and I imagine that there are lots of 
people with the same problem, so any help would be very much appreciated...

Thanks,

João Saleiro
