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 2014-10-16 10:06:53 UTC 
Description of problem:
Fails to lookup users and groups with case_sensitive=preserving in proxy provider

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: uid=User_CS1,ou=Users,dc=example,dc=com
objectClass: posixAccount
objectClass: account
cn: User_CS1
homeDirectory: /home/User_CS1
uid: User_CS1_Alias
uid: User_CS1
uidNumber: 304560
gidNumber: 304560

2. Configure sssd as proxy backend and add case_sensitive=preserving in the domain section:
[domain/PROXY]
debug_level=0xFFF0
id_provider = proxy
proxy_lib_name = ldap
proxy_pam_target = sssdproxyldap
case_sensitive = preserving

3. Lookup an user

Actual results:
Lookup fails to return anything.
# getent -s sss passwd User_CS1
# 

Domain log shows:
(Thu Oct 16 14:44:57 2014) [sssd[be[PROXY]]] [be_get_account_info] (0x0200): Got request for [4097][1][name=user_cs1]
(Thu Oct 16 14:44:57 2014) [sssd[be[PROXY]]] [get_pw_name] (0x0400): Searching user by name (user_cs1)
(Thu Oct 16 14:44:57 2014) [sssd[be[PROXY]]] [handle_getpw_result] (0x0080): User not found.
(Thu Oct 16 14:44:57 2014) [sssd[be[PROXY]]] [delete_user] (0x0400): User user_cs1 does not exist (or is invalid) on remote server, deleting!


But, looking up directly from nss_ldap shows:
# getent -s ldap passwd User_CS1
User_CS1:*:304560:304560:User_CS1:/home/User_CS1:

Expected results:

Comment 5 Kaushik Banerjee 2014-11-25 18:14:12 UTC 
The result is still the same. Tested with sssd-1.12.2-26.el7

# getent passwd User_CS1;echo $?
2

# getent -s ldap  passwd User_CS1
User_CS1:*:304560:304560:User_CS1:/home/User_CS1:

(Tue Nov 25 13:08:07 2014) [sssd[be[PROXY]]] [be_req_set_domain] (0x0400): Changing request domain from [PROXY] to [PROXY]

Comment 6 Michal Zidek 2014-11-26 12:53:12 UTC 
Hi,

sorry I did not properly read the name of this bugzilla (I started reading the problem description in the comments).

If you want to use proxy_lib_name = ldap, then make sure you put this line to
nscld.conf:
ignorecase yes

Case-insensitive proxy will not work properly with case sensitive nscld. Such configuration could be ambiguous. So this bugzilla's name was invalid from the beginning.

However the description was a valid bug. SSSD really did not work with case_sensitive = preserving (actually it also did not work for case_sensitive = false). And that was the bug that was fixed upstream now.

Sorry I should have noticed that earlier.

Michal
Comment 7 Kaushik Banerjee 2014-11-28 12:58:20 UTC 
Works fine with "ignorecase yes" in nslcd.conf.

Thanks Michal. You can change the status of this bug to ON_QA again.
