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 Kaushik Banerjee 2012-11-08 15:57:03 UTC

Description of problem:
user id lookup fails with proxy provider

Version-Release number of selected component (if applicable):
1.9.2-7

How reproducible:
Always

Steps to Reproduce:
1. Add a user and group in ldap as:
Group1 --> puser1

2. Setup sssd.conf for proxy provider as:
[domain/PROXY]
id_provider = proxy
debug_level = 0xFFF0
proxy_lib_name = ldap
proxy_pam_target = sssdproxyldap

3. # getent group Group1
Group1:*:2001:puser1

# id puser1
id: puser1: No such user

Note: You need to run it in correct order as:
# getent group Group1;id puser1
  
Actual results:
"id puser1" fails.

Expected results:
"id puser1" should work.
