I have a stand-alone NeXT with the system booting from a 330 meg hard-disk. Up till a week ago, I had two accounts on the machine, "root" and "me" as well as a certain number of invisible accounts (such as daemon). Recently I added a new account for my son who is visiting. The problem is that he seems to lack certain crucial permissions that the "me" account has. For example, he couldn't read the file "article.sty" which is needed by the latex program until I "chmod"ed it so that "other" as well as "user" and "group' could use it. Also, when one gives the su command from his account, one gets a permission denied message; from the "me' account one gets a request for a password. So my question has two parts:1) What groups other than "other" does "me' belong to; 2) How do I give the new account membership in these groups as well. Thanks very much for any help with this.

The group you want to belong to is the 'wheel' group. Do the following to add users to the wheel group or any group for that matter. nidump group . > lala modify the file! Put users in or take them out of the groups! Wheel is the one where you can su and all that good stuff! Then you have to reload the file! niload group . < lala That should do it!

There are a couple of possible errors/bugs/problems that might be the case here: a) sometimes the usermanager seems to give an arbitrary group to a new/modified account, it happened more than once that after changing some information, I suddenly had bin as my primary group. This is a BUG. b) me, as it is intended to be the only account on a single user system that works for UNIX-unaware users, has a lot of privileges that a normal user account should not neccessarily have. e.g. it is member of the group wheel. Some protections of files are set incorrectly, as far as I know. This can also create problems. c) using su is allowed for everybody, unless it is used to su to root, in which case you have to be in the wheel group. If you want to give this privilege, then make at least sure that wheel is not the primary group, because files created by this user also have the wheel group which might cause some problems... To add more groups to an existing user, you need to use either the nidump niload pair of programs or use netinfomanager. With nidump you can create a UNIX-style ascii file that looks like the /etc/group file. You just append user names to the end that starts with the group you want to be in. With niload you can load it back into the netinfo databse. If you use netinfomanager, just add the names of the users to the /groups/GROUPNAME entry under the users property. At the latest after a reboot all the changes should take effect. To look in which groups you are just issue the groups command in any shell or terminal window. I hope this helps.
