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 Chino Soliard 2021-12-01 17:32:39 UTC 
Description of problem:

  In RHEL8.5, when following the following KCS:

    How to configure a Samba server with SSSD in RHEL
    with Winbind handling AD Join 
    [*] https://access.redhat.com/solutions/3802321

  The command...

    realm join domain.net --user=administrator --client-software=sssd --membership-software=samba

  ... fails giving no details.

  After some test, we can isolate the issue to the following version:

    - RHEL8.5
    - samba.4.14.5-2.el8.x86_64

  The same problem is *not* present in:

    - RHEL8.4
    - samba.4.14.5-2.el8.x86_64

  As a workaround, the solution is to downgrade to:

    - samba.4.13.3-4.el8_4.x86_64

  And this also downgrade other packages.

How reproducible:

Following the KCS, after step 2 (installing requried packages).

Steps to Reproduce:
1. Yum update; yum install (the required packages -smb,sssd,etc.-)
    # yum install realmd oddjob oddjob-mkhomedir sssd adcli samba samba-winbind krb5-workstation

2. Attemt a realm join using --membership-software=samba
    # realm -vvv join domain.net --user=administrator --client-software=sssd --membership-software=samba

Actual results:

    # realm -vvv join domain.net --user=administrator --client-software=sssd --membership-software=samba
     * Resolving: _ldap._tcp.domain.net
     * Performing LDAP DSE lookup on: 10.2.10.10
     * Performing LDAP DSE lookup on: 10.4.10.10
     * Performing LDAP DSE lookup on: 10.5.10.10
     * Successfully discovered: domain.net
    Password for administrador:
     * Required files: /usr/sbin/oddjobd, /usr/libexec/oddjob/mkhomedir, /usr/sbin/sssd, /usr/bin/net
     * LANG=C LOGNAME=root /usr/bin/net -s /var/cache/realmd/realmd-smb-conf.3XH1D1 -U sv_pdldap -k ads join domain.net createcomputer=example_group/example/linux
    Enter administrador's password: ! Failed to enroll machine in realm: Process was terminated with signal: 11
    realm: Couldn't join realm: Failed to enroll machine in realm. See diagnostics.
    Please check

Expected results:

   "Successful joined the domain"

Comment 1 Sumit Bose 2021-12-15 12:37:12 UTC 
Hi,

there should be a coredump of the net command, please ask the customer for the coredump or at least for output of 'coredumpctl dump' (assuming the crash of the net command is the latest). For the latter it would be good to install Samba's debuginfo packages.

bye,
Sumit

Is that helpful?
Comment 7 Sumit Bose 2022-01-14 09:51:11 UTC 
Hi,

please try to add a systemd config snippet /usr/lib/systemd/system/realmd.service.d/core_limit.conf which contains:

    [Service]
    LimitCORE=infinity

and call

    systemctl daemon-reload
    systemctl stop realmd.service

The next time realmd is called there should be no core dump limit anymore.

HTH

bye,
Sumit
