I tried to create a profile in a asp.net page in an ASP.NET application I am developing.  For some reason, I get the error that states: Login failed for user 'SQLUser'. The user is not associated with a trusted SQL Server connection.  Whenever I try to create a userid/password for a website I am developing, I get that error.  What do I have to do to get rid of the error?

you must first check that the sql server instance you connect to is in mixed authentication mode, to allow sql logins.
in the default "windows authentication only", it only allows windows-based logins to connect.

how do I check to see if it is in mixed authentication mode after it has already been installed?

How do I set the database to be mixed authentication?  I tried to set myself as the user to login and when I create a user with a userid and password... I get no dice.

Yes, I saw that I could set it as mixed authentication mode.  Is this is what is stopping me from moving forward on my project?

Is it the connection string?  Here is what I have so far:

<!--Connection String-->
  <connectionStrings>
    <add name="EmpScreeningConnStr" connectionString="Data Source=(local);Initial Catalog=EmpScreening;User ID=bsmith9;Password=password"
      providerName="System.Data.SqlClient" />
  </connectionStrings>
  <appSettings />

that seems fine, IF the authentication mode is set to mixed, AND if you created that login (bsmith9) in your sql server's security->logins, AND if you mapped that login to a user in the database EmpScreening (and you also need to grant permissions/roles to that user...)

This is what I found for authentication:

 <!--Authentication-->
    <authentication mode="Forms">
      <forms loginUrl="Login.aspx"></forms>            
    </authentication>

Whoa, how do I do all of that?  I have this for authentication:
<!--Authentication-->
    <authentication mode="Forms">
      <forms loginUrl="Login.aspx"></forms>            
    </authentication>

How do I set it to mixed mode?

I'm a little bit lost and I am wondering why I keep on getting the

Login failed for user 'SQLUser'. The user is not associated with a trusted SQL Server connection. error.  What is the solution for this?  I took this from another developer's computer and it seemed to work fine on his computer, fast forward to now, and I am unable to get it to work on my computer.  This is very frustrating actually and I am trying every different option I can think of.  Do I have to adjust the web.config..that is where the user info is beinig rejected.

on the IIS for your web server, you have to configure the web site to disallow anonymous connections.
