Hi Techies

I have general question more similar to single sign on of sharepoint
site.

I have two asp.net sites SiteA and SiteB with forms authentication
enabled. Lets assume its available in same server. SiteA and SiteB
users and credential informations are same.

If UserA logged in SiteA using some credential, the same credential
must be used to authenticate SiteB from client side. How we can
acheive this?

In another way, the SiteA will have links to SiteB, when I click the
link I want to skip the login page of SiteB since I know the
credentials for SiteB, I want to internally authenticate from SiteA.
Is it possible?

Any help would be appreciated much,
Thanks
Sudha

Hi Sudha,
one way you can go if your applications are sitting on the same server is to 
modify directory structure. Create one virtual directory with two 
subdirectories (also virtual). Put your application into those sub 
directories and login page into top directory. 
Another more common way is described in Altair's post on Code Project as 
already Braulio mentioned. This technique can be used only if your 
application shares same subdomain.
If your application do not share subdomain you have to implement third 
applicaton wich will log on users to your other applications. This is 
possible if you  use cookiless authentication tickets and 
enableCrossAppRedirects set to true:
   <authentication mode="Forms">
    <forms cookieless="UseUri" enableCrossAppRedirects="true" ... />
   </authentication>

Regards,
Ladislav
