While generating the below output, I noticed that you're missing a ':'
in your /etc/user_attr line. Try adding that, and see if it works.
After you've done that, you can check the privileges on your shell with ppriv:
ultra20$ ppriv $$
146999: -ksh
flags = <none>
E: basic
I: basic
P: basic
L: all
ultra20$
The above shell has only the basic privileges. You should see
something like this:
ultra20$ ppriv $$
147444: -ksh
flags = <none>
E: basic,dtrace_kernel,dtrace_proc,dtrace_user
I: basic,dtrace_kernel,dtrace_proc,dtrace_user
P: basic,dtrace_kernel,dtrace_proc,dtrace_user
L: all
ultra20$
