We are rolling out our first .net 4.0 entity framework application and are having an issue with security.
We have it working on our alpha site inside our development environment with the following setup:
- SQL2005
- IIS6
- .NET 4.0
- asp.net mvc 2
- Entity Framework
- NTLM
But when we moved it to our production environment for beta testing we are getting the following error via asp.net
SqlException (0x80131904): Cannot open database "our database name" requested by the login. The login failed. Login failed for user 'Domain\User'.
The only difference between the between the 2 environments is we are using Kerberos instead of NTLM in our production environment. We have several other .net 3.5 sites using LinqToSql that run on both environments.
We have already done the following:
- Replaced an active user on another test site with the user that is failing to make sure it isn't an issue with the way the user is set up. - worked
- Dropped and re-added the user from sql2005 - did nothing
The issue appears to be related to .net 4.0 as this is our first...
