This might be the best answer -- reformat and create his account first,
then yours.

HOWEVER before you completely give up, notice that the first administrative
account is a member of all sorts of groups. It's been awhile since I
looked, but is the second administrative account a member of all the same
groups? For example the adm group lets you view the logs in /var/log and
the sudo group lets you use sudo, but there are some other groups -- my
admin account is a member of cdrom dip plugdev lpadmin and sambashare, too.
I haven't looked them all up but you could try making sure he's a member of
all the same groups.
