cd permission woes
This seemed like a newbe question so I am placing it here.
I have a group that I create with groupadd. There is no corresponding user. I have added several users to the group by editing the /etc/group file so that it looks like:
I have a directory that is owned by root:root and has permission set 777. Inside this directory, I have a subdirectory owned by root:<group> with permission set as 770.
As <user3>, I can get to the first mentioned directory above, but can not get to the subdirectory. However, if I su, and then su <user3>, I can then get it.
Please expand my understanding so I can correct this.
