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 Viktor Ashirov 2018-11-27 23:48:53 UTC 
Description of problem:
When dscreate is executed in verbose mode, it prints Directory Manager's password to stderr. The same happens with dsconf when I change the password.

Version-Release number of selected component (if applicable):
389-ds-base-1.4.0.19-2.

How reproducible:
always

Steps to Reproduce:
1. dscreate -v interactive
2. dsconf -v localhost directory_manager password_change

Actual results:

# dscreate -v interactive
...
DEBUG: cn=config set REPLACE: ('nsslapd-rootpw', 'Directory_Manager_Password')


# dsconf -v localhost directory_manager password_change
...
Enter new directory manager password : 
CONFIRM - Enter new directory manager password : 
DEBUG: cn=config set REPLACE: ('nsslapd-rootpw', 'new_password')

Expected results:
Actual value should not be printed in the debug logs. Python logging module supports filters that should be used to redact sensitive information from the logs

Build tested: 389-ds-base-1.4.1.3-2.module+el8.1.0+3395+60a28832.x86_64

I see that the following attributes are correctly replaced during modification: 

 44 # Attributes that should be masked from logging output
 45 SENSITIVE_ATTRS = ['userpassword',
 46                    'nsslapd-rootpw',
 47                    'nsds5replicacredentials',
 48                    'nsmultiplexorcredentials']

DEBUG: cn=config set REPLACE: ('nsslapd-rootpw', '********')
