I found the NIS option located under the box where I set the root password scary.
I don't want the root password to be distributed by NIS (in case it breaks!). I'd prefer another window after this grouping NIS, LDAP (and why not, samba options?). I also found my SiS 620 based PC having rare lines under the cursor (following it , like a shadow effect : in fact I wonder if these lines are not a mirroring effect from some windows in the screen?) that disappears when I walk it on the edge of the screen. All the rest went fine.
