By this user I trying to launch command on freeipa host:
/usr/sbin/dmidecode -t bios -t baseboard -t system -t processor -t memory > file.txt
answer: Permission denied.
How to give permissions in freeipa server to do it? Or how to give 777 mod to files from freeipa for some users?
As an option, you can use sudo -i to not prefix each command with sudo.
I recommend to refrain from spoiling file system permissions as much as possible.
Otherwise may result in various security and integrity related issues.
