Grapple Roll Question

[Xedrek]

Does initiating and maintaining a grapple auto-fail or succeed on a 1?
If so could you point me at the official ruling, or page for it

[Nefreet]

It's an attack roll.

Attack rolls auto fail on a 1.

second paragraph of Performing a Combat Maneuver section wrote:

When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target's Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.

Even Bruno, a handsome and beautiful Tetori, has been defeated by a stupid dumdum natural one.
