FormsAuthenticationTicket and user data

[Tarun Mistry]

Hi all, I am using the ASP.NET 2.0 security model to impliment user access
control on my site. I have a few questions hopefully someone can answer:

1) From the encrypted ticket stored in the cookie (available in
User.Identity) how can I access the users userId value?

2) If a user is logged in, is the corresponding information in the
aspnet_user and membership tables loaded somewhere that can be accessed?

3) Can the aspnet_user and membership tables be extended to hold some site
specific information?

Thanks for any and all help,
Taz
