Hello,
i have a sharepoint 2013 farm with 2 managed metadata service (MMS) applications. When opening the Term Store Management Tool in Central Admin (CA) I can only edit one of both MMS applications. It is always the same MMS application and it does not matter which of the 2 MMS applications i select in the CA. The URL parameter of the termstoremanager.aspx is different in both requests. One time the URL looks like http://SERVER:2013/_layouts/15/termstoremanager.aspx?tsid=d59a32f8-ef8c-4f61-ad25-f0bec173b348 the other time the URL looks like http://SERVER:2013/_layouts/15/termstoremanager.aspx?tsid=ad2d54da-3e4a-450e-84ff-2ce43512a931
When i modify the tsid URL parameter to a different guid it has no impact. The Term Store Management Tool always displays the same MMS Application. The dropdown "Available Service Applications" in the Term Store Management Tool only brings up one MMS application.
The weird thing is, that i can Manage the second termstore with the termstore management tool of a content webapplication that is associated with the second MMS. That looks like a bug inside the CA.
I could experience this behaviour in 2 different sharepoint 2013 farms, so this seems something that can be reproduced. Both farms have the march 2013 PU installed.
Can anyone confirm this behaviour?
