  • Update main.yml

    Hi @Mayfly277, thanks for your work!
    I am proposing this change because for what I tested and read on few blogs, NTLMv1 downgrade attacks cannot be made on MEEREEN if LmCompatibilityLevel is 3. 
    I tested both configurations and I was able to do NTLM downgrade on MEEREEN with LmCompatibilityLevel 2.
    
    Cheers,
    
    Diego
