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 2018-02-05 16:28:32 UTC

Description of problem:
SSSD makes LDAP queries which are encrypted using kerberos/gssapi. This means that the LDAP queries cannot easily be investgated using tcpdump or wireshark, even when the decrypt kerberos packets option is used with the host keytab file.
It would be useful for debugging purposes to see exactly what LDAP queries are being made and to which servers. Also the results from these queries.

The existing debug output from SSSD is quite helpful in this respect, but it would be better if a small enhancement were made so that for a specific debug level ( eg 0x0400), SSSD would print out all the details of the LDAP search it is doing, ie the LDAP server IP(and port), the base dn, the scope, filter and attributes requested. Currently the server and filter are printed on two different lines at different debug levels and there is no indication of base dn, scope or attributes used in the search. Similarly if the raw results could be displayed (maybe use a different debug level for that in case a large number of results are returned).

This would be extremely useful in debugging what is requested by SSSD and what is returned by the AD server. Although it is possible to turn on event log debugging on the AD servers themselves, that is not practical in a large environment where there are literally millions of requests each day and the event log would fill far too quickly to be of use.

Version-Release number of selected component (if applicable):
sssd-client-1.14.0-43.el7.x86_64

Comment 6 Jakub Hrozek 2018-02-21 16:50:35 UTC

I would say we should provides probes for e.g. systemtap so that the admin can watch the LDAP searches. I don't think debug messages are the right place.

Please see man sssd-systemtap for example of what is already supported (sorry, I don't know if RHEL already has the man page, here is a link to upstream: https://jhrozek.fedorapeople.org/sssd/1.16.0/man/sssd-systemtap.5.html)

Chances are the probes might even do what the customer wants or that the existing probes need to be adjusted, but I think it's a better way of fulfilling the request than the debug messages.

+1.
It will be really handy for troubleshooting.

Comment 13 Martin Kosek 2019-03-12 13:07:36 UTC

Updating RFE title, to reflect the adjusted scope - adding systemtap probes.

Comment 21 Amith 2020-01-23 13:37:18 UTC

Verified the bug with SSSD Version: sssd-2.2.3-11.el8.x86_64

Steps followed during verification:

1. On one terminal, execute *.stp scripts from /usr/share/sssd/systemtap/* directory.

2. After the execution of script, on another terminal run user/group lookup commands like ID / GETENT PASSWD <USER>.

See results below:

Terminal 1 : 
# sss_cache -E ; getent passwd testuser1
