His authority is that he is the Palpatine's right hand man and enforcer. We see him command and take the initiative several times to serve the Emperor throughout ANH and Rebels. He is not going to consult with Sheev on every action he is going to take. To bring it back to R1, if Vader thought Krennic was more fit to defend the DS than Tarkin presumably he could give Krennic the command. Now he can't just do this because he likes Krennic better rather it must best serve the Emperor's own interests.
Ultimately, nothing in the film nor the novelization suggests Vader has consulted with Sheev prior to his conversation with Krennic. It appears that these are Vader's commands not Palpatine's direct commands. Whereas in RotJ he makes it clear that he is expresssing the Emperor's commands.
Tarkin would be his "superior" as he commands the DS. It's akin to a General deferring to the captain of a naval vessel.

Nah, the novel has Krennic saying: "Does that mean I'm still in command? You'll speak to the Emperor - " right before Vader cuts him off with a choke.
Which underlines the point: unless what Vader says comes straight from Palpatine himself, Tarkin is supreme.
And your comparison about generals/captains is flawed. Vader exists outside the chain of command and so would have no hierarchical reason to defer to Tarkin unless Tarkin himself simply wields more authority than Vader.
Again, this is why Tarkin gives orders throughout ANH without hesitation or fear and Vader takes them without hesitation or reprisal. Vader is not the sort of man to bark orders at... unless he's expected to obey them.
Now I can buy that they're essentially equals and Vader takes Tarkin's shit out of a profound mutual respect for the man, but the implication that Tarkin > Vader is far more bountiful than the reverse. Tarkin is not subordinate to Vader, period.
He says the same thing in the movie as well. What Krennic wants Vader to speak to the Emperor about is not clarified, however considering he was previously asking Vader to get him an audience with the Emperor it seems that is what he was going to ask about once more. It certainly does not seem to be about the Emperor putting him back in charge as his first question assumes that is already the case.
The comparison is certainly not perfect but the jist of it works specifically because it is about authority and not rank. On board his own vessel the commander wields more authority (but still does not outrank) than those who generally wield more.
Not at all. I'll repeat because you have yet to provide evidence to the contrary, Krennic believes Vader can put him in command of the DS and we have no reason to believe this comes from the Emperor himself (other than your own notions on how the Imperial hierarchy works.) Regardless, it's clear we will not come to an understand on this topic so it will be my last post on it.
