Integrating SSO with Active Directory using dynamic controller discovery

Hi there,

Is there a way to integrate application security to get SSO functionality with authentication/authorization done via Active Directory, but with controller address being dynamically discovered using DNS-based methods? As described for example here: http://technet.microsoft.com/en-us/l...50(WS.10).aspx

? All examples I've seen rely on domain controller's address given explicitly in the application context configuration...

Additionaly I have a forest of domains, but it's step two of my problem ;)

I would greatly appreciated any assistance in this matter...

Regards,
Wojtek
