I have one old app (ActiveDir Manager, targetting Android 1.6) that I haven't found a newer alternative for and which I've been using for a long time, which does that on Android 6.x. No big deal, but it was kinda freaky the first time.
This app lets you manage AD on your phone, though there may be a security concern with what credentials you enter into it.

I've used it in the past during an upgrade project but I changed the password pretty regularly on the account I used with it. I wouldn't enter the default domain admin account on it.
