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:
 The LDAP backend is not properly parsing sudoOptions. In at least one instance, this results in selinux roles not being applied.


Version-Release number of selected component (if applicable):
 sudo-1.8.25p1-4.el8_0

How reproducible:
 Difficult, without a full LDAP server backend configuration

Steps to Reproduce:
1. Configure an LDAP server which includes a sudoOptions configuration to allow escalation to a particular selinux role

    sudoOption:role=sysadm_r
 
2. Access a system that is using the LDAP server for authentication services, where the user is in an SELinux user confined state as staff_r

3. Attempt to transition using 'sudo -i' to acquire the sysadm_r role

    # sudo -i
    # id -Z


Actual results:
    # sudo -i
    # id -Z
    staff_u:staff_r:staff_t:s0

Expected results:
    # sudo -i
    # id -Z
    sysadm_u:sysadm_r:sysadm_t:s0


Additional info:
 The following commit from the upstream project has been identified as resolving the condition.

    Fixed a bug in the sudoers LDAP back-end parsing the 
    command_timeout, role, type, privs and limitprivs sudoOptions. This also 
    affected cvtsudoers conversion from LDIF to sudoers or JSON.
