All, This was odd, but understandable. zypper up on 15.4 tonight produced the following warning on mariadb update: /usr/lib64/mysql/plugin/auth_pam_tool_dir/auth_pam_tool: on an insecure path - /usr/lib64/mysql/plugin/auth_pam_tool_dir has different non-root owner who could tamper with the file. Well, not quite the hair-on-fire tamper opening you would expect. The parent directory owner is our good friend mysql from days gone by which I suspect has just been happily carried over release after release, etc... The directory in question: l /usr/lib64/mysql/plugin/auth_pam_tool_dir total 20 drwxr-x--- 2 root mysql 4096 Oct 4 01:41 . drwxr-xr-x 3 root root 4096 Oct 4 01:41 .. -rwsr-xr-x 1 root root 10408 Sep 16 05:12 auth_pam_tool So if this is even worth worrying about, it looks like the warning needs to be fixed somewhere to recognize group mysql as the proper group for directory ownership. -- David C.
