Send credentials/user information accross applcations securely?

I have three separate applications setup on an IIS server. Let’s call them
AppA, AppB, and AppC. On AppA (the Default application) the user is presented
with a login window. The login information is stored in a SQL Database.
Depending on the user’s credentials they can be routed to AppB or AppC. I
need to securely pass the user’s login name and unique identifier to either
AppB or AppC. How can I, in ASP.NET, securely pass this information to the
applications? I can send the information in the query string, but I don’t
know how to secure this. Can I use a web service and the
System.Security .Cryptography class? Any help is appreciated.

Hi, I'm writing this off the top of my head as I don't have the exact information to hand. We are attempting to set up a secure internet site using ASP.NET on IIS5. We are having some authentication problems early on in the project. The plan is to have 1 ASP.NET (IIS) forms application serving user requests and another ASP.NET (IIS) webservice interfacing to the database.

Hello, I have been desperately trying to programmatically authenticate a windows user, create their credentials, and then redirect them to a different server while passing the credentials at the same time so that they don't have to login again.

I have an win form app from which I want to be able to send bug reports.

Hi. I would like to let users send bug reports or other messages to me. Maybe the easiest way to send e-mails from my application is just use the default e-mail agent by executing a link mailto://mymail@domail.com. But this only works if the user has configured Outlook or something. Many users use web-based mails here so if I do so, Outlook Express's a new account wizard will pop-up. Futhure more this reveals user e-mails. Some people...

We use a Soap Header to pass a token class (m_Token) back and forth with authenticated session information. Given the following implementation for our Logout method, I vastly prefer to simply code m_Token = null in order to destroy the session token when the user logs out. However, I'm finding that setting class instance to null results in no header being sent back to the client, with the result that the client actually remains with an...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it.
