User john is a member of both webcamd and vboxusers: # grep john /etc/group webcamd:*:145:john vboxusers:*:920:john When the file /tmp/my-test is owned by webcamd, user john can touch it ok: $ ls -l /tmp/my-test ; touch /tmp/my-test -rw-rw---- 1 vboxusers vboxusers 0 Aug 15 12:54 /tmp/my-test But when /tmp/my-test is owned by webcamd, user john gets an error: $ ls -l /tmp/my-test ; touch /tmp/my-test -rw-rw---- 1 webcamd webcamd 0 Aug 15 13:02 /tmp/my-test touch: /tmp/my-test: Permission denied Why does this error occur? Two groups seem identical. Just different group ids. Filesystem is UFS: /dev/ad10s1a on / (ufs, NFS exported, local) Yuri
