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 of problem:
netgroup lookups returned in lowercase with case_sensitive=preserving

Version-Release number of selected component (if applicable):
sssd-1.12.1-3.el7

How reproducible:
Always

Steps to Reproduce:
1. Add the following ldif to ldap server:
dn: cn=NetGroup_CS1,ou=Netgroups,dc=example,dc=com
objectClass: nisNetgroup
cn: NetGroup_CS1_Alias
cn: NetGroup_CS1
nisNetgroupTriple: (Host1.example.com,User1,example.com)

2. Confiure sssd with case_sensitive=false

3. Lookup netgroup
getent netgroup netgroup_cs1


Actual results:
# getent netgroup netgroup_cs1

Hi,

I looked into this and I see this as NOTABUG. The reason is that we do not control the format of netgroup name in the getnetgr response packet. The packet only contains netgroup triples. The name of netgroup printed on the screen is always in the same case as the name entered by user when invoking getent.

So there is not much we can do about this, preserve and false will always behave the same with netgroups.

Michal

Sorry I confused two bugzillas when asking for the ack.

As Michal said, the netgroup protocol is a bit odd from libc point of view. The case-sensitiveness is only used to select the netgroup with setnetgrent. The name that we print is completely under libc control.

Therefore, I'm closing this bug as CANTFIX.
