Just complete the Quest: No Gods, No Masters. This is the last mission of the Yes Man storyline, right after jumpstarting the Lucky 38.

A few suggestions,
Make sure you are well equiped to fight the legate, he is a tough enemy even for a lvl 30, he is also surrounded by Praetorian Guards which utalize balistic fists. You can also avoid the fight with him using a 100 speech option.
Followers are quite helpful, I brought ED-E and Boone with me, they owned.
Also heavy damage weapons such as a anti-material rife can punch through his armor, you can get some from dead legion members on your way to the camp.
You can avoid a fight with the general of the NCR by having 85 speech and discussing the boomers, or going with the 100 speech option. But the securatrons should waste him easily so he is not a threat.
