ASA5510 Clientless VPN SSO RDWEB OWA CIFS

Question

Hi!
I´m trying to use single sign on in clientless vpn portal. I have my bookmarks in place (rdweb/web servers and cifs share). I would like to just enter user/pass just one time (at the portal loginpage of asa5510). I use radius for my auth (radius auth running on a win2008r2 with nap policy). 
I have seen on other posts that i should put &csco_sso=1parameter after the url string in bookmark settings but that doesnt work. I also tried the post settings CSCO_WEBVPN_USERNAME & CSCO_WEBVPN_PASSWORD
Do i need to specify single signon server in Group policy i use for clientless vpn? In that case what should i specify?
Servername: Just any name or the fqdn?
Authentication type: I dont have any siteminder solution in place so my options are SAML POST
Settings
Assertion URL: ?
Issuer: ?
Cert:
Do i need to set up a ADFS 2.0 role on my network to use SSO server feature at the asa5510?
Regards,
Fredrik

Answer 1

A couple of updates:
3. I added our nbns server to the Cisco config, and now clicking the Browse entire network button shows me the domain.  However, when I click on the domain, it says "Failed to retrieve servers".  A had a support tech look at this, and he said the config all looks fine, and he found a few other instances of this for other users.  He's investigating and will get back to me.
4. This looks like it's possible through content-rewrite rules (http://www.cisco.com/c/en/us/td/docs/security/asa/asa84/asdm64/configuration_guide/asdm_64_config/vpn_clientless_ssl.html#wp2389515)  
"By default, the security appliance rewrites, or transforms, all clientless traffic. You might not want some applications and web resources (for example, public websites) to go through the ASA. The ASA therefore lets you create rewrite rules that let users browse certain sites and applications without going through the ASA. This is similar to split-tunneling in an IPSec VPN connection."
Whether this will work in combination with SSO is the question, but I'll play around and see what I find.  :-)
