1006463 – sudo -U <user> listing shows incorrect list when sssd is used.

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 Najmuddin Chirammal 2013-09-10 16:18:41 UTC

Description of problem:

As root, if I try to list the rules allowed for a user, then it returns incorrect/incomplete list. 
Running sudo -l as normal user returns correct results.

For example: 

As root: 

# sudo -l -U luser1
User luser1 may run the following commands on this host:
    (ALL) /bin/fdisk

As normal user: 

$ sudo -l
User luser1 may run the following commands on this host:
    (ALL) /bin/fdisk
    (ALL) /usr/bin/passwd

Version-Release number of selected component : sudo-1.8.6p3-8.el6.x86_64.rpm


How reproducible: Always


Steps to Reproduce:
1. Configure nsswitch to use sudo rules from SSSD.
2. Try to list the rules allowed using a netgroup membership.
3. 

Actual results: 'sudo -U -l' try to match the netgroup entry with 'root' username instead of the actual user, and the rules allowed via netgroup are 
missing.

Expected results: 'sudo -U -l' lists all rules.


Additional info: 

- The rules are listed properly if 'ldap' is used instead of 'sss'
