ASIP no password required

I have appleshare ip 6.3.3 on OS 9.1 on 1 mac G3. also 1 mac G4 is in the house via filesharing in OSX. I doesn't ask for a user or password in osx 10.2.6? It shows m admin user name but i can only clikc on 'ok' and it lets me go. i can log in with anything i type as a password and thats a security hazzard. I'd like to use 1 login for both macs if possible ;( So why does it not as me for an admin password when in os 9 i hav to use it everywhere? Thanks vazdef@hotmail.com
