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 afox@redhat.com 2019-03-04 13:07:31 UTC

Description of problem:
In customer environment, there is an AD domain which spans 5 datacenters, with two AD DCs in each datacenter for a total of 20 AD DCs.

There are firewalls limiting connectivity between the datacenters, which means that AD clients in datacenterA cannot contact the AD DCs in datacenterB and vice versa. However, the AD DCs are able to communicate with each other.

When the command 'adcli --verbose info -D our.ad.domain' is executed in automation to identify the computer-site and subsequently join to the site local AD DC, adcli only sends the netlogin pings to 5 of the 20 AD DCs. As a result,  when none of the local AD DCs is pinged, the computer-site cannot be identified, and the automation fails.

Version-Release number of selected component (if applicable):
adcli-0.8.1-4.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Setup an AD domain that contains more than 5 AD DCs. 
2. Run adcli command as above. 

Actual results:
Only 5 AD DCs are pinged

Expected results:
All AD DCs should be pinged
