how can i use /usr/ucb/ps to give the full user

Hi,
on solaris I need the full ps output, and process this. With /usr/ucb/ps auxwww I get the output as wanted, but the user is cut off to 8 long.
With ps -o ruser I can get the full username, but I do not have the full output.

Is it possible to get long output, with the full username?

Thanks in advance

I am not aware of one, such that on the systems I have worked on the usernames are kept down to 7 or 8 characters in length.
