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.

Fixed In Version: sssd-1.2.1-35.el6
Doc Type: Bug Fix
Doc Text:
On 32-bit architectures, running the "getent passwd" command on a username with a very large user or group identifier (that is, UID or GID greater than 2147483647) resulted in an empty output. With this update, the underlying source code has been modified to address this issue, and the getent command now returns the expected output.

Description Gowrishankar Rajaiyan 2010-10-21 14:22:30 UTC 
Description of problem:
On 32bit platforms 'getent passwd <username>' returns nothing if its uidNumber > 2147483647.

Version-Release number of selected component (if applicable):
sssd-1.2.1-32.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Setup a LDAP server.
2. Add users and groups with very high uidNumber/gidNumber. ( gt 2147483647)
3. Configure sssd with id_provider = ldap.
4. getent passwd username
  
Actual results:
No results for <username>.

Expected results:
Users/groups with high uidNumber/gidNumber should be returned successfully.

Additional info:

1. This works fine on 64bit platforms.

2. This is reproducible on RHEL5.6 32bit platforms as well.

3. Relevant config section of sssd
[domain/LDAP]
id_provider = ldap
auth_provider = ldap
ldap_uri = ldaps://sssdldap.idm.lab.bos.redhat.com:636
ldap_search_base = dc=example,dc=com
cache_credentials = true
enumerate = true
debug_level = 9
ldap_tls_cacertdir = /etc/openldap/cacerts
ldap_tls_cacert = /etc/openldap/cacerts/cacert.asc
