smbnetfs cannot access libsecret unless run in foreground

[Matthew R. Dorozenski]

Ubuntu 21.10
smbnetfs/impish,now 0.6.3-1 amd64

I am using smbnetfs to mount smb network shares. Credentials are stored in libsecret using secret-tools. Server name myserver. Share name public is unprotected. Share name myshare is protected by password. If I run:

smbnetfs mnt

there are no errors, and I can browse to public shares.

cd mnt/myserver/public
ls

gives the expected result and lists contents.

However,

cd mnt/myserver/myshare
ls

gives:

ls: cannot open directory 'mnt/myserver/myshare': Permission denied

However, if I run with either the -d (debug) or -f (foreground) option, (-d implies -f), and then in another terminal, or by backgrounding the running process, I run the above commands, I am able to browse both public and password protected shares without issue.

I suspect this has something to do with the ability to access information stored in libsecret when run in the background, but I'm not certain.

Everything works as expected if I use a .auth file for the credential storage (which is obviously less secure, but I tested it to help diagnose the issue).

Also - a side note - the -o use_libsecret option listed in the manual and with --help both error:

fuse: unknown option `use_libsecret=true'

If the option is set in the .smb/smbnetfs.conf file, the same error is reported. However, run in the foreground, without this option, libsecret is used correctly.
