User Log In Without Supplying Password On Localhost?
Feb 21, 2011
I have a Asp.net web site built on C# with Forms Authentication. We use an Active Directory to authenticate the users, and everything works fine. But today we realized that it's possible to login to any account by just entering the username and click Login, without supplying any password! This is only happening on the development environment running on localhost , but I don't like it...
I've never seen this behaviour before, and would really like someone to explain how this could happen. Is this a developer feature built by Microsoft? Or did someone at my office make a backdoor without telling the rest? I will investigate this last option further, but until then - have anyone encountered this before?
My company has some unique password policies (such as a pwd cannot be re-used for 6 months, aside from the must include #, special character, upper & lower case)Can anyone suggest how to go about ensuring that a new user's password complies with these policies (using forms authentication in .net 3.5 framework)?

I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure

I have an ASP.Net 4.0 application that is using Forms Authentication and ActiveDirectoryMembershipProvider. It authenticates against Active Directory running on Windows Server 2008 R2.I use ChangePassword control for changing passwords.When the user changes the password he can log on for some time with the old password. My client feels this is a security problem with the application. Is there any way to make sure the old password does not work after the user changes it?Also, if I do iisreset on the web server, the old password stops working. The password must be cached somewhere in the web app.
