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.

Description Marek Haicman 2017-02-06 10:40:29 UTC 
Description of problem:
Current implementation of kinit does not echo any character when entering password. From my perspective, this has security implications - by not giving user ANY feedback, it is more prone for leaking password.

Simple exemplary situation - wrong window focused, on different monitor.


Proposal:
Provide user with option to enable echoing asterisks, as usual, or cycle through few characters to show activity, without giving password length in easy way. (for example randomly print one of the characters .oO :) )

Version-Release number of selected component (if applicable):
krb5-workstation-1.14.1-27.el7_3.x86_64
Comment 2 Robbie Harwood 2017-02-06 17:31:03 UTC 
This is how most password tools on unix-likes (e.g., passwd and friends) behave, so there isn't a very large impetus to change this behavior.  Certainly the default will not change.
