Azerbaijan and Luxembourg are both still searching for their first wins of their 2014 World Cup qualifying campaigns after sharing the points in Baku.
Hosts Azerbaijan, having hit the woodwork twice in the opening 25 minutes, took the lead in the battle of Group F's bottom two nations in the 71st minute when Ruslan Abishov headed home Araz Abdullayev's cross from the right.
However, that lasted just nine minutes before Stefano Bensi drew Luxembourg level, the striker firing home his first goal for his country with a low shot from the edge of the area.
Azerbaijan were reduced to 10 men four minutes later when Branimir Subasic was handed a straight red card for a foul on Mario Mutsch, but Luxembourg could not make the most of their man advantage to force a winner as the two nations drew for the second time in qualifying.
The result leaves Luxembourg with three points from six games, while Azerbaijan have one more point but have played a game extra.
