User names & password issues

Ok, on RedHat7.2 it would seem you can create usernames with capital letters and they can be longer than 8 characters. _If_ I create users with more than 8 characters is it going to screw up things along the road - Samba? Windows/Linux issues? I'm thinking of a sensible naming policy for a school. More than 8 characters would be nice I guess - but not if it'll mean having to perform workarounds later. ---- Secondly, how can I tell RedHat user manager to allow null passwords, or short passwords? There are some accounts that I don't want a password for. Cheers all -- Mat __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
