I see the same problem with Ubuntu 20.04 and 22.04, inside an Active Directory
domain.
With slow machines (e.g. with rotational hard disks) it is always present; with
fast machines (with SSDs) it is randomly present, maybe because it depends also
on the time needed to contact the domain controller.
(I'm using a cinnamon desktop and I do not have ibus installed)
I have applied the following workaround:
copy /usr/lib/systemd/user/gvfs-daemon.service to
/etc/systemd/user/gvfs-daemon.service
insert in the last file the following line, at the start of the [Service]
section:
ExecStartPre=bash -c "for i in echo {1..20} ; do if [ $(env | grep
KRB5CCNAME) == "" ]; then sleep 0.2 ; fi ; done"
In this way it is possible to browse the network with Nemo or Nautilus,
without asking for user authentication.
When the workaround is not present I see this message in
/var/log/syslog:
Mar 30 10:30:36 pc000327 gvfsd[2656]: got no contact to IPC$
Mar 30 10:30:39 pc000327 gvfsd[2672]: Kerberos auth with 'aduser@WORKGROUP'
(WORKGROUP\aduser) to access '10.1.0.107' not possible
(Here kerberos is not aware of the real domain name and tries the
generic WORKGROUP)
I report here also the relevant processes in the case of no workaround:

The difference that I can see is that in the first case gvfsd is started
before cinnamon-session, while in the latter case gvfsd is started after
cinnamon-session.

Title:
Nautilus does not use a valid Kerberos ticket when accessing Samba
share
Status in gvfs:
Unknown
Status in gvfs package in Ubuntu:
Triaged
Bug description:
Nautilus prompts for username and password when accessing a Samba
share on a network drive, despite having a perfectly valid unexpired
Kerberos ticket. 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.
