Just checked with 2.14.2 where i can see both the fields enabled. Can you try selecting another ESXi Host (or storage) and check please?
yes.. odd thing.. no matter which host or which datastore I choose. I have the same result.. I event tried different browser think it may be browser related.
I figured out the issue. It appears that somehow a configuration setting was either reset or removed.
Under "Configuration - Machine managers" the "Mount ESXi" option was uncheck. It was checked previously so why it was uncheck baffles me.
I am now able to publish the templates out correctly. I'm guessing it was stuck in limbo as I had it before and then it wasn't but the username and password still stored in the DB.
regardless it's working now.
