386i, SNAP

[Mai Zhou]

I have a stand alone 386i that I bought two weeks ago.  I try to create a
new account for myself when logging in it ask me name and password but
after running for a few seconds it stops and say see your system
administrator.  

1: How can I enable this feature?

2: I login as super user and try to use SNAP, only two options are
   available: backup and restore. I tried to change the etc/group and
   etc/passwd file so that when I login (not as super user) and type "groups"
   it said accounts operator networks devices but still only two options
   available. How can I use other snap function?

THANK you in advance.
