Trusted Authentication fails with Code First
--------------------------------------------
Key: DNET-893
URL: http://tracker.firebirdsql.org/browse/DNET-893
Project: .NET Data provider
Issue Type: Bug
Affects Versions: 6.7.0.0
Environment: Windows 10, Firebird Super Server 2.5, Visual Studio
2019, Entity Framework 6.1.3, Code First
Reporter: LC Arch Team
Assignee: Jiri Cincura
*Observed Behavior:
Querying the database via LINQ to entities fails with an
InvalidOperationException: No user name was specified.
*Expected Behavior*
No exception
*Cause*
FbProviderServices.GetDbProviderManifestToken creates a new connection through
FbServerProperties if the given DbConnection is not already open.
FbServerProperties, or more specifically its base classe, FbService does not
support Trusted Authentication. FbService.Open specifically checks for the
existence of a user name and password and throws an exception.
FbService.cs:
{code}
protected void Open()
{
if (State != FbServiceState.Closed)
throw new InvalidOperationException("Service
already Open.");
if (string.IsNullOrEmpty(_csManager.UserID))
throw new InvalidOperationException("No user
name was specified.");
if (string.IsNullOrEmpty(_csManager.Password))
throw new InvalidOperationException("No user
password was specified.");
{code}
By contrast, FbConnectionInternal first checks for the existence of a user name
and password, and branches into trusted authentication.
FbConnectionInternal.cs:
{code}
public void Connect()
{
if (Charset.GetCharset(this.options.Charset) == null)
throw new FbException("Invalid character set specified");
try
{
this.db = ClientFactory.CreateDatabase(this.options);
this.db.Charset = Charset.GetCharset(this.options.Charset);
this.db.Dialect = (short) this.options.Dialect;
this.db.PacketSize = this.options.PacketSize;
DatabaseParameterBuffer dpb = this.BuildDpb(this.db, this.options);
if (this.options.FallIntoTrustedAuth)
this.db.AttachWithTrustedAuth(dpb, this.options.DataSource,
this.options.Port, this.options.Database);
else
this.db.Attach(dpb, this.options.DataSource, this.options.Port,
this.options.Database);
}
{code}
*Workaround*
Opening the connection manually before passing it into DbContext is a
workaround.
