The <Faddeev-Popov ghost field> couples to both the <gauge field> and the <adjoint scalar field>. In a convention with $D_\mu=\partial_\mu+[A_\mu,\cdot]$, the ghost action after <integration by parts> contains $f^{abc}(\partial_\mu\bar c^a)A_\mu^b c^c$ and $f^{abc}(n\cdot\partial\bar c^a)\phi^b c^c/\sqrt2$.
