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:
When sssd is in offline mode and a request comes in to a data provider, an attempt to connect to the server is only made if the last attempt was 60 or more seconds ago.
This mechanism and the specific hardcoded timeout are not found in the documentation. It is important to have this documented, so, for example, system administrators could predict when the clients will restore the connection after the server comes back online.
Version-Release number of selected component (if applicable):
sssd-client-1.9.2-41.el6.x86_64
libsss_idmap-1.9.2-41.el6.x86_64
libsss_sudo-1.9.2-41.el6.x86_64
sudo-1.8.6p3-6.el6.x86_64
sssd-1.9.2-41.el6.x86_64
Verified in version sssd-1.12.2-39.el7
man sssd.conf has:
offline_timeout (integer)
When SSSD switches to offline mode the amount of time before it
tries to go back online will increase based upon the time spent
disconnected. This value is in seconds and calculated by the
following:
offline_timeout + random_offset
The random offset can increment up to 30 seconds. After each
unsuccessful attempt to go online, the new interval is recalculated
by the following:
new_interval = old_interval*2 + random_offset
Note that the maximum length of each interval is currently limited
to one hour. If the calculated length of new_interval is greater
than an hour, it will be forced to one hour.
Default: 60
