Hi.

I know i should be posting this in General Forum but it is having something to Cookies and Multiple Domains issue, i am posting this link here for reference. Point # 6 states

6. Cross-domain authentication support: (as of version 1.3.8) although cookies are domain specific, the newest version of mod_auth_tkt allows initial tickets to be passed via URLs, allowing single-signon across completely unrelated domains (www.foo.com and www.bar.com).

the URL to this apache module is:

http://www.openfusion.com.au/labs/mod_auth_tkt/

Could this be it?

Thanks
Anup
