I have mysql5.5.20 on my windows machine. I am not able to execute following command:
groupadd mysql
useradd -G mysql mysql
I am doing this because I am configuring Nakamura(Sakai) for MySql and I found these commands at: https://confluence.sakaiproject.org/display/KERNDOC/Configuring+Nakamura+for+MySQL
Thanks for help!
