Hi Elias, 

I expect you are using authentication and that you have it enabled on the GridFs database. Is this correct?

Which version MongoDB are you using ?

Hi, Norberto

Correct i'm GridFs using to save images, using only authentication connection as shown in the example:
mongodb://name:pa...@mongodb.server.com/test?Safe=false
It has some kind of authentication should I use before saving a file in GridFs?

The version 2.1.1 is MongoDB

I am unable to reproduce this.

Can you show me how you are calling Upload?

Normally credentials provided on the connection string flow down as default credentials from server to database to GridFS, but if you are doing something unusual the credentials might not be reaching the Upload call.

What version of the C# driver (not the server) are you using?

I also recommend that you always use "safe=true" in your connection string instead of "safe=false".

Hi Robert Stam,

 

The error occurs when trying to insert any document also.

MongoDB.Driver C # version 1.4.2.4500

The following screenshot with error.

Thanks for the additional info.

This error is a result of a change made to the server (versions 2.1.0 and newer) that resulted in an incompatibility with older versions of the C# driver when using authentication. Specifically, newer versions of the server require that the getLastError command (that's the command that gets sent to the server when safe=true) be sent to the authenticated database. With previous versions of the server the driver would just sent the getLastError command to the admin database no matter which database the update operation had actually occurred on.

See: https://jira.mongodb.org/browse/CSHARP-521

This was fixed in version 1.6 of the C# driver which was released on 2012-08-12.

You are using version 1.4.2 which does not contain the fix.

Thanks Robert Stam,
I switched to the new Driver, worked perfectly.

Thank you again.
