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.

Cause: The host based access control part of SSSD treated all its attributes as plain strings Consequence: case-insensitive comparisons of attributes such as host group names would fail in case they contained UTF-8 characters Fix: The SSSD host based access control provider utilizes libunistring for performing string comparisons where applicable Result: SSSD is able to handle UTF-8 strings in host based access control rules

Description Stephen Gallagher 2011-07-28 17:45:24 UTC 
Description of problem:
Hosts, hostgroups and other attributes of IPA HBAC rules may have names in non-English UTF-8 languages. We need to support comparisons against these rules.

Version-Release number of selected component (if applicable):
sssd-1.5.1-43.el6

How reproducible:
Every time

Steps to Reproduce:
Use extended UTF-8 characters in a hostname or hostgroup in IPA's LDAP.
  
Actual results:
Case-insensitive omparisons fail against UTF-8 characters.

Expected results:
UTF-8 should be handled correctly.
