"TF14045: identifier <guid> is not a recognized identifier" after collecting the project from TFS 2010 to 2012

Question

I cannot access the Source control in Visual Studio 2010, since in 2012, when I try to access this error, it displays: "TF14045: authentication is not a recognized identity." This error started after I disconnected the project collection from TFS 2010 and joined Team Foundation Server 2012, does anyone know how to fix this?

Answer 1

I think you have installed TFS 2012 with Update 1? If so, you need to wait for the update, which will contain a fix for this error. Take a look at Microsoft Social:

Answer 2

There has never been this error, because the migration is planned for January, but I found this entry with some suggestions and answers from MS:

Answer 3

Just make sure you have not opened two instances of Visual Studio and are trying to connect two TFS servers that need two different credentials / domain.

I ran into this problem and, closing one of the instances, started working fine.
