I think he probably told her. And Sakura. Considering she knows about the forehead poke. But he also probably told them how he didn't want anyone else to know, because he doesn't want anyone else's name to be ruined. And they probably decided to respect his wishes. I'm almost certain he told Sakura, but still 50/50 on Sarada.

Though there is a way for people to know the truth, without the Uchiha name being tarnished. Obito (1 Uchiha who had "broken ties" with the rest) unleashed Kurama on Konoha. Danzo deliberately refused to let the Uchiha help defend the village. Then he tried putting Blame on them, causing suspicion and contemt from the rest of the village. Then put them into a little corner on constant surveillance. And just kept putting more and more fuel on the fire before finally the clan snapped. It's not a big stretch to say he would have done anything to get rid of the Uchiha. He just used Itachi to do it. But the fact that in the Anime, the Anbu were heading over to stop the revolt right at the same time Itachi and Obito killed everyone, means the Uchiha were probably planning to revolt later that night or the next morning. Danzo could have had his Foundation in wait to attack and they would have killed everyone including Sasuke. Itachi being the one to do it meant Sasuke could live. So basically the real fault is all on Danzo and Obito.
