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the product is no longer active in Red Hat Bugzilla.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 of problem:
We have multiple testcase failures related to failover wherein the list of URI's have different port numbers. These cases worked in RHEL-8.0.0. Following are the cases:
1. ldap uri failover with single server different ports
2. ldap chpass uri failover with single server different ports
3. ldap chpass backup uri failover with single server different ports
Version-Release number of selected component (if applicable):
sssd-2.2.0-19.el8
How reproducible:
Always.
Steps to Reproduce:
1. Setup SSSD with any one of the following domain section:
[domain/LDAP]
debug_level=0xFFF0
id_provider = ldap
ldap_uri = ldap://$SERVER1:12345,ldap://$SERVER1:389
ldap_tls_cacertdir = /etc/openldap/certs
ldap_search_base = dc=example,dc=com
OR
[domain/LDAP]
debug_level=0xFFF0
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
ldap_uri = ldap://$SERVER1
ldap_chpass_uri = ldap://$SERVER1:12345,ldap://$SERVER1:389
ldap_tls_cacertdir = /etc/openldap/certs
ldap_search_base = dc=example,dc=com
OR
[domain/LDAP]
debug_level=0xFFF0
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
ldap_uri = ldap://$SERVER1
ldap_chpass_uri = ldap://$SERVER1:12345
ldap_chpass_backup_uri = ldap://$SERVER1:389
ldap_tls_cacertdir = /etc/openldap/certs
ldap_search_base = dc=example,dc=com
2. In the above cases, port 12345 is non-existent in order to allow SSSD to failover to next uri or backup uri. Now restart SSSD service.
3. Run a user login. You will see that user auth fails. SSSD log shows "PORT NOT WORKING" error.
Additional info:
A similar bug related to krb5_kpasswd exists (https://bugzilla.redhat.com/show_bug.cgi?id=880546). This bug was fixed and is part of our automation. Strangely, all the krb cases related to "Single server different port" works.
Verified the bug on SSSD version: sssd-2.2.3-16.el8.x86_64
This bug was part of regression run failure hence following beaker job should cover the verification:
