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.

Comment 2 Stephen Gallagher 2011-02-03 17:33:42 UTC 
We are going to drop the -p option as it's not advisable to pass the password on the command-line anyway.
Comment 5 Gowrishankar Rajaiyan 2011-03-21 07:02:36 UTC 
Verified that "-p" option has been dropped.

[root@pogolinux-2 ~]# sss_obfuscate -d LDAP -p
Usage: sss_obfuscate [options]

sss_obfuscate: error: no such option: -p


[root@pogolinux-2 ~]# sss_obfuscate -h
Usage: sss_obfuscate [options]

sss_obfuscate converts a given password into
human-unreadable format and places it into
appropriate domain section of the SSSD config
file. The password can be passed in by stdin,
specified on the command-line or entered
interactively

Options:
  -h, --help            show this help message and exit
  -s, --stdin           Read the password from stdin.
  -d DOMNAME, --domain=DOMNAME
                        The domain to use the password in (mandatory)
  -f FILE, --file=FILE  Set input file to FILE (default: Use system default,
                        usually /etc/sssd/sssd.conf)
