SQL异常 - 用户“UserName $”登录失败

Question

I am having an issue with one of my pages that is pulling content from a database which is displayed in <select> tags. I have seen many others with this issue but haven't seen anyone's have a $ after the user. I am not sure why it is adding a $. I have redone my connection string, .dbml file and have even created a user AD\\INFO4420$ in my database and have given it read and write privileges. When using Visual Studios I am able to run the page and there is no error but it only occurs when viewing it from the server.

The Error is as follows:

Login failed for user 'AD\\INFO4420W$'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'AD\\INFO4420W$'.

Connection String in my Web.config:

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-Final_Project-20131204200025;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-Final_Project-20131204200025.mdf"
      providerName="System.Data.SqlClient" />
    <add name="TowingApp_dbConnectionString" connectionString="Data Source=INFO4420W.ad.uvu.edu;Initial Catalog=TowingApp_db; Integrated Security=true"
      providerName="System.Data.SqlClient" />
  </connectionStrings>

I know the program is using the following as the connection string. Any time I comment out the following it throws another error.

<add name="TowingApp_dbConnectionString" connectionString="Data Source=INFO4420W.ad.uvu.edu;Initial Catalog=TowingApp_db; Integrated Security=true"
          providerName="System.Data.SqlClient" />

Any help or direction would be appreciated!

Answer 1

You're using integrated security Integrated Security=true . It works locally because your local windows account has access to local SQL Server DB. Perhaps you have to switch to SQL Server authentication with dedicated ID and password.

In that case instead of Integrated Security=true you would specify

User ID=YourUserid;Password=YourPassword;

My guess the ID/Password should be provided to you by the univercity. Also to avoid having ID and password in open text either supply them from code or encrypt the connection string.
