The following link might be helpful: http://www.maclife.com/article/columns/terminal_101_creating_new_users

And this script gives further information and examples: http://wiki.freegeek.org/index.php/Mac_OSX_adduser_script

According to that, the following commands should do it:

dscl . create /Users/otrs
dscl . create /Users/otrs RealName "OTRS user"
dscl . create /Users/otrs NFSHomeDirectory /opt/otrs
dseditgroup -o edit -t user -a otrs nogroup
dseditgroup -o edit -t user -a otrs otrs
dseditgroup -o edit -t user -a otrs www-data
