Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
My apologies, I didn't provide the rest of the documentation where we tried without quotes:
[user@houlenv0 ~]$ ksu root -e ls /root
Authenticated user
Account root: authorization for user for execution of
ls successful
Changing uid to root (0)
ksu: Permission denied while trying to execv ls
And then with single quotes just in case:
[user@houlenv0 ~]$ ksu root -e 'ls /root'
Authenticated user
Account root: authorization for user for execution of
ls /root successful
Changing uid to root (0)
ksu: Permission denied while trying to execv ls /root
BUT specifying the full path of the command does work:
[user@houlenv0 ~]$ ksu -e /bin/ls /root
Authenticated USER
Account root: authorization for USER for execution of
/bin/ls successful
Changing uid to root (0)
anaconda-ks.cfg
So from "man ksu":
-e command [args ...]
ksu proceeds exactly the same as if it was invoked without the
-e option, except instead of executing the target shell, ksu
executes the specified command. Example of usage:
ksu bob -e ls -lag
...
The commands listed after the principal name must be either a
full path names or just the program name. In the second case,
CMD_PATH specifying the location of authorized programs must be
defined at the compilation time of ksu. Which command gets exe‐
cuted?
We will check their CMD_PATH.
