[NoCat] Read owners from the server?

[kyleena at tele2.it]

Hi all,
I have a terrible question! I hope someone of you could 
help me: I would like that the owners'list could stay in 
the server...
I try to explain: I have NoCat server and NoCat gateway on 
two separate machines. I use Radius for authentication, 
and a Postgres database to store informations. Everything 
works great. On the gateway, I set MembersOnly = 1 because 
I don't want anybody can skip authentication. With 
TrustedGroups = Any, everyone authenticates is logged in 
as Member... and it's ok.
But now, I would like that the server could send some 
attribute to tell the gateway: "this one is an Owner!" 
I've tried to send a NoCat-Groups or a NoCat-Groups-Admin 
attribute (I naturally included dictionary.nocat in the 
Radius' dictionary file), but it seems that the gateway 
totally ignores the attributes that the server sends. 
Infact, if I set TrustedGroups = NOCAT, and the user that 
authenticates is in NOCAT group, the gateway admit him in 
the Public class.
My problem is that I will not have the gateway at office, 
but only the server. I wrote a simple PHP web interface to 
permit my remote gateway admin to insert and delete his 
users. But, at this time, he can't insert any Owner - 
because NoCat reads the Owners'list only from nocat.conf 
on the gateway.
I know that my question is very strange, but I would 
appreciate if anybody can address me: what file can I 
modify to made this change? It's very important to me! 
Please help...
Thanks
Monica
