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the product is no longer active in Red Hat Bugzilla.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:
Testing Multiple Graphical Login
1. Install RHEL desktop on multiple virtual or bare metal machines.
2. Edit the /etc/dconf/profile/user file on every client. If one does not already exist, create it.
3. Add a line containing service-db:keyfile/user to the file and save your changes.
4. Setup shared /home directory via NFS on each machine. Put the following line into /etc/fstab
nest.test.redhat.com:/mnt/qa/scratch/rhel7-gnome-shell-shared-home /home nfs rw 0 0
5. Create account with username "test" and password "redhat".
6. Login to Gnome.
SELinux is preventing /usr/sbin/useradd from 'setattr' accesses on the file .bash_logout.
***** Plugin catchall_boolean (89.3 confidence) suggests ******************
If you want to allow use to nfs home dirs
Then you must tell SELinux about this by enabling the 'use_nfs_home_dirs' boolean.
You can read 'None' man page for more details.
Do
setsebool -P use_nfs_home_dirs 1
***** Plugin catchall (11.6 confidence) suggests **************************
If you believe that useradd should be allowed setattr access on the .bash_logout file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep useradd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
