Hi
If you can log in using Windows Authentication, then it means that an account for the ASP.NET user (or the impersonated user) has been created in MS SQL. This should not be the case.
In order to disable Windows Authentication in myLittleAdmin, edit your config.xml file (located in myLittleAdmin install folder) and in the myLittleAdmin\connection\authentications node, remove the line
Code:<authentication value="windows" name="lWindowAuthentication" localization="true" />
