I'm not sure if this is a Linux capabilities problem, a PAM problem, or what, but I've noticed that If I add a user to > 32 groups...that user cannot access anything in a directory owned by a group > the 32nd group.
Has anyone else experienced this?
Here is a sample script to help troubleshoot if you're interested:
#!/bin/bash x=34; useradd testuser while [ ! $x -lt 1 ] do groupadd group$x gpasswd -a testuser group$x x=$(( $x - 1 )) done
groups read printf "press any key..." groups testuser printf "press any key..." read mkdir /testdir chown root:group1 /testdir chmod 770 /testdir su - testuser -c "ls /testdir" printf "press any key..." read userdel -r testuser
If all has gone properly, and group1 is *not* in the first groups listing, (not "groups testuser"), then the user will not be able to even ls /testdir, and you'll get permission denied.
Please advise, if you can. TIA.
