Without entering into any further detail about what a daemon is, I'll just show how to list them under a privileged (root) Solaris terminal by means of the standard shell command ps(1):
# ps -o user,uid,pid,ppid,pgid,sid,tty,args -t '?' \
|(IFS=''; read H; echo "$H"; sort -k5 -k3 \
|grep filtering_options account )

A basic description of each chosen column is on the aforementioned manpage, but it was driven by an interest towards daemon programming. One will note that the main filtering criteria is the absence ('?') of a controlling terminal (TT) and that the output was sorted first by process groups (PGID) and then by process ids (PID). Perhaps one will also note (with the help of Intro(2) manpage) that in this listing each process is a member of the first process group in/of each session because its PGID and SID are equal.
