System.Data.SqlClient.SqlException: Login failed for user

Question

Working with my project in debug I have no issues. However running it in IIS I am getting this error:

System.Data.SqlClient.SqlException: Login failed for us

Answer 1

Just set Integrated Security=False and it will work ,according to a comment difference between True and False is:

True ignores User ID and Password if provided and uses those of the running process, SSPI(Security Support Provider Interface ) it will use them if provided which is why MS prefers this. They are equivalent in that they use the same security mechanism to authenticate but that is it.
