This variable is set by pam_sss when the user authenticates and can be used by other processes, such as gio, to skip the credentials input when accessing network shares, for example. Some services rely on gvfs-daemon in order to properly function, such as tracker-extract-3.service and tracker-miner-fs-3.service, which means they will ask for the gvfs-daemon to be initialized when they are executed by systemd. This creates problems if one service that relies on gvfsd is started too early, as it would result in gvfsd being started too early as well. As of version 3.1 of tracker-miners, the install target of tracker- miners-fs-3.service was set to gnome-session.target: https://gitlab.gnome.org/GNOME/tracker-miners/-/merge_requests/283 However, the tracker-extract-3.service was not updated and its target is still default.target, which is too early for the service to start. Starting tracker-extract too early is also starting gvfsd too early, before the session environment gets fully updated. Which means that gvfsd does not have the KRB5CCNAME variable and can not do any operations with it. Tracker-extract is supposed to be a helper service managed by tracker- miner-fs-3.service. By using a [Install] section, we are actually telling systemd that it should manage this service as well, when it shouldn't. So, by removing the [Install] section and having tracker-miner- fs-3.service being tied to gnome-session.target, we fix the issue of gvfsd starting too early without the updated session environment. [ Test Plan ] In order to test this issue, it's required to have an Active Directory server running. 1) Authenticate with an AD user (as this would set the KRB5CCNAME env); 2) Check gvfsd environment. This can be done by running: cat /proc/$(pidof gvfsd)/environ | xargs --null -n1 You will be able to see that it does not have the variable listed. 3) Check that the information mentioned above about tracker-miner-fs- 3.service is true. 4) Disable tracker-extract-3.service (This is a bit tricky, since its target was default.target. The easiest way is to remove the symlink that systemd created when enabling the unit, located under /etc/systemd/user/default.target.wants/tracker-extract-3.service 5) Reboot the machine; 6) Repeat steps 1 and 2. This will show that gvfsd is now started with the proper environment. Is not enough to look at ptree and the pids of the processes, instead it's better to look into the session logs with: journalctl --user -b And check the order in which the services were started and when they were triggered. Test packages are available in the following ppa: https://launchpad.net/~mruffell/+archive/ubuntu/sf320070-test After installing test packages of tracker-miners, KRB5CCNAME should be set in gvfs environment upon login to gnome. [ Where problems could occur ] The tracker project is a search engine that speeds up search operations in Gnome. The tracker-miners is the indexing daemon that populates the database with information, so changing its start does not affect the system behavior. This changes fix the startup of gvfs-daemon.service, which could delay services that relied on it running to be executed.

The Kerberos ticket is obtained automatically at logon by authentication against a Samba Active Directory server (Samba AD-DC). Accessing the same Samba share with the same Kerberos ticket via "smbclient //host/sharename -k" works fine. One known workaround is: "nautilus -q", and then "killall gvfsd". After that, accessing the Samba share with Nautilus works normally as it should. I did not experience this issue in Ubuntu 16.04. It appears that a regression was introduced somewhere between 16.04 and 18.04. The issue is quite annoying and confusing for the users who are used to accessing Samba shares on the network drive without being prompted for their username and password. The issue appears to manifest itself usually not on the first access to a Samba share, but on subsequent accesses after a system reboot or upon user logout/login. Strangely, removing ~/.cache/ibus/bus/registry file before user login appears to fix the issue for the current user session, but then the problem reappears upon subsequent user logins or after a system reboot. Nemo appears to have the same problem as Nautilus.
