824616 – sssd_nss crashes when configured with use_fully_qualified_names = true

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:
sssd_nss crashes when configured with use_fully_qualified_names = true

Version-Release number of selected component (if applicable):
sssd-1.8.0-29.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. Add users/groups on ldap server as follows:
 
dn: uid=user1,ou=People,dc=example,dc=com
cn: User1
uid: user1
uidNumber: 3000
gidNumber: 3000
homeDirectory: /export/user1
objectClass: top
objectClass: posixAccount
 
dn: uid=user2,ou=People,dc=example,dc=com
cn: User2
uid: user2
uidNumber: 3001
gidNumber: 3001
homeDirectory: /export/user2
objectClass: top
objectClass: posixAccount
 
dn: cn=child,ou=Groups,dc=example,dc=com
gidNumber: 4001
objectClass: top
objectClass: groupofuniquenames
objectClass: posixgroup
cn: child
memberUid: user2
 
dn: cn=parent,ou=Groups,dc=example,dc=com
gidNumber: 4000
objectClass: top
objectClass: groupofuniquenames
objectClass: posixgroup
cn: parent
memberUid: child
memberUid: user1
 

2. Configure sssd for lookup via proxy provider:
 
[domain/PROXY]
id_provider = proxy
proxy_lib_name = ldap
proxy_pam_target = sssdproxyldap
enumerate = true
debug_level = 0xFFF0
use_fully_qualified_names = TRUE
cache_credentials = TRUE
 
3. Lookup group
# getent -s ldap group child
child:*:4001:user2

# getent -s sss group child@PROXY   <== crashes here

Actual results:
sssd_nss crashes

Expected results:
sssd_nss should not crash

Patch is available upstream and is trivial (simple typo).

Comment 7 Amith 2012-05-29 14:11:34 UTC

Verified the bug on sssd-1.8.0-31.el6. This bug was discovered during the automation runs on RHEL-6.3 i386 and ppc64 architecutures against sssd version:1.8.0-28.el6.
