I have a connection string for Entity framework with sql authentication

<add name="Entities" connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MA000XSXXXXX\Sample;Initial Catalog=Test;User ID=temp;Password=temp;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/>

While running the application i was ended up with this error
Error:
The underlying provider failed on Open.
While googling i found that trying to connect the database through sql authentication may lead up to this error.But I have only windows authentication access to my database.
So i want to convert the above connection string to access the database using windows authentication.

I tried removing the userid and password attribute from the connection string, but the error still persist.

Please help
Thanks in advance!!!

Happy sighs!!!

Ha ha ha, I forgot to add the windows authentication attribute

Trusted_Connection=Yes;
or
Integrated Security=SSPI;

to my connection string, sometimes I let the stress to win :(
Now i got rid of the error be adding the Trusted_Connection attribute to my connection string and removed credentials details.

<add name="Entities" connectionString="metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=MA000XSXXXXX\Sample;Initial Catalog=Test; Trusted_Connection=Yes; MultipleActiveResultSets=True&amp;quot;" providerName="System.Data.EntityClient"/>

Now it works good.
