primary & secondary group

hi! I'm new to solaris.

I would like to know how do i add a user into a primary group and multiple secondary group using command line? Can give an example on that?

Another question is how do i assign rights to a user using command line? eg. how do i assign "primary administrator" role/rights to a user using command line? Thanks.
