I'd appreciate a definitive answer to this question too. One thing it does do is to use default.unix instead of default.c2 as default in /etc/auth/system. I use neither -- I think I added some extra default permissions to mine -- those of you who read the script I use to process /etc/passwd would have noticed that I don't put explicit permissions in /tcb/files/auth/?/* but just set the default to include the permissions I want since it's a lot easier to maintain things that way -- in case SecureWare decide to increase the number of explicit permissions needed at some future downgrade, I can just adjust it in one place. Actually, I hope by then I'd have another UNIX. Does anyone know if u_secclass does anything in the current SCO releases ? I remember someone saying that making it "d" and rebooting made a difference to them (was it Brandon?) but I can't seem to find any difference. Happy New Year to one and all. Even the guys at SecureWare. Yeah, why not. -- ronald@robobar.co.uk +44 81 991 1142 (O) +44 71 229 7741 (H)
