[Test Case] 1. With an AD deployed, and having the machine registered, include the following option in sssd.conf: # This option should only be used to test the machine account renewal task. The option expect 2 integers seperated by a colon (':'). The first integer defines the interval in # seconds how often the task is run. The second specifies the inital timeout in seconds before the task is run for the first time after startup. # Default: 86400:750 (24h and 15m) ad_machine_account_password_renewal_opts = 5:5 2. Restart the service and monitor the use of descriptors: root@sssd-xenial:/home/ubuntu# while true; do ll /proc/$(pidof sssd_be)/fd | wc -l; sleep 60; done 38 50 62 74 86 98 110 122 134 146 158 170 182 194 206 217 229 ^C [Other info] The bug is reported and fixed upstream: https://pagure.io/SSSD/sssd/issue/3017 Upstream fix commit: https://pagure.io/SSSD/sssd/c/312d211e03b9f3769a0362f1767cc59792e32746 Trusty is not affected (feat not implemented) and A/B/C already include the fix : $ git describe 312d211e03b9f3769a0362f1767cc59792e32746 sssd-1_13_4-10-g312d211e0 $ rmadison sssd ==> sssd | 1.13.4-1ubuntu1.10 | xenial-updates sssd | 1.15.3-2ubuntu1 | artful sssd | 1.16.1-1ubuntu1 | bionic sssd | 1.16.1-1ubuntu1 | cosmic sssd | 1.16.1-1ubuntu3 | cosmic-proposed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1771805/+subscriptions -- Mailing list: https://launchpad.net/~sts-sponsors Post to : [email protected] Unsubscribe : https://launchpad.net/~sts-sponsors More help : https://help.launchpad.net/ListHelp
