 /etc/shadow group ownership chages with "passwd" command Whenever any normal user changes their password, the /etc/shadow file changes group ownership to user's primary group. Any ideas why this is happening and how to correct? # uname -a HP-UX xxxx B.11.11 U 9000/800 stcdwhpd unlimited-user license xxxx:/etc # ls -la|grep shadow -r-------- 1 root sys 1657 Jan 5 17:06 oshadow -r-------- 1 root sys 1657 Jan 6 08:28 shadow # groups jdoe uss # grep 200 /etc/group uss::200: # groups root adm bin daemon lp mail other root sys users xxxx:/etc # su - jdoe [1] % passwd Changing password for jdoe Old password: New password: Re-enter new password: Passwd successfully changed [2] % exit xxxx:/etc # ls -la|grep shadow -r-------- 1 root sys 1657 Jan 6 08:28 oshadow -r-------- 1 root uss 1657 Jan 6 08:30 shadow      |

| Re: /etc/shadow group ownership chages with "passwd" command Just to rule out the possibility that someone has removed and replaced the passwd command, you should verify the checksum of the passwd command: cksum `which passwd` Compare this with the original checksum. That's one possibility. |

| Re: /etc/shadow group ownership chages with "passwd" command Since the file remains read only by owner (root), it is not a big deal. Probably a bug in the program as it is creating a new file and running suid but not sgid.
