PtrToStructure may return null if currentInteractPtr equals IntPtr.Zero, resulting in dereferencing null in interactChallenge.saslChallengeType. The SaslInteractionProcedure is a callback invoked by native LDAP library, so pointer parameters may be IntPtr.Zero in error scenarios. Add null checks for interactPtr, currentInteractPtr, and interactChallenge before member access to prevent NullReferenceException.
