The Kaiser, who stepped down as club president late last year, has been linked with Bayern for the past 51 years as an extremely successful player, coach and president.
Strangely enough, Beckenbauer, one of Germany's all-time greats who won the World Cup as a player and a coach, never had a testimonial after leaving the Bavarians he had joined as a teenager in 1959 to play for the New York Cosmos in 1977.
Ribery, who extended his contract with the German League and Cup double winners to 2015 after their Champions League defeat by Inter Milan in May's final, was a constant threat on the left and was brought down in the box in the eighth minute.
Real coach Jose Mourinho, who moved from Inter after this year's Champions League win, was without injured Brazilian playmaker Kaka but his star-studded line-up included Cristiano Ronaldo, Xabi Alonso and new signing Angel di Maria.
"We need tough opponents like Bayern. We need these matches ahead of the season. But you saw we still have a bit to go," Mourinho said.
"We have two weeks to go and I hope we will use them to put it all together," he said.
