Comment 5 for bug 1096661

is libpam-smbpass still available/required? i don't see such a package

https://packages.ubuntu.com/search?keywords=smb&searchon=names&suite=impish&section=all
https://packages.ubuntu.com/search?suite=impish&section=all&arch=any&keywords=samba&searchon=names

but i am having the problem that i can't authenticate to see a share that works when it is set to guest

i fit in the category of knowing i need samba but not knowing how it works. in this case, ubuntu 21.10 nautilus-share installed it for me as far as i remember, when i right clicked to create a local network share. but i think i have installed it pre-emptively/manually in previous installs.
