Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Jakub Hrozek 2017-03-22 20:47:36 UTC 
This bug is created as a clone of upstream ticket:
https://pagure.io/SSSD/sssd/issue/3331

SSSD configuration:
```text
    [sssd]
    config_file_version = 2
    services = nss, pam
    domains = $AD_DOMAIN1

    [domain/$AD_DOMAIN1]
    ldap_purge_cache_timeout = 0
    krb5_auth_timeout = 12

    debug_level = 0xfff0
    id_provider = ad
    use_fully_qualified_names = True
    krb5_auth_timeout = 15
    access_provider=ad
    ad_access_filter=(cn=user1_dom1-${JOB_ID})
```

AD domains:

* AD_DOMAIN1=sssdad.com
* AD_DOMAIN2=sssdad_tree.com
* AD_DOMAIN3=child1.sssdad.com

How to reproduce:

1. join sssd to AD_DOMAIN1
2. configure based on provided template
3. authenticate with various users from all domains user1_dom1-${JOB_ID}@$AD_DOMAIN1 user2_dom1-${JOB_ID}@$AD_DOMAIN1 user1_dom2-${JOB_ID}@$AD_DOMAIN2 user1_dom3-${JOB_ID}@$AD_DOMAIN3

Expected result:
Just first user is allowed and rest will get pam error code  6 (Permission denied)

```

Actual result
User from AD_DOMAIN2 get pam error code:  10 (User not known to the underlying authentication module)
