无法打开登录请求的数据库“test”。 登录失败。 用户 'Domain\\userid' 登录失败

Question

I have website hosted in IIS with application pool identity set to 'Local systems'.
Windows authentication - Enabled
ASP .net Impersonation - Enabled
all other are disabled
ASP.net impersonation identity set to Authenticated user.

I am getting error:

Cannot open database "test" requested by the login. The login failed. Login failed for user 'PRD\\12345'.

<add name="testConnectionString" 
     connectionString="Data Source=testserver;Initial Catalog=test;Integrated Security=True" 
     providerName="System.Data.SqlClient" /> 

This is my connection string

Answer 1

Have you also created a User in the database mapped to the login? If the login has not been at a minimum granted the CONNECT DATABASE permissions then it will not be able to connect when a specific database is included in the connection string
