Comment 0 for bug 1801227

In Kodi, try to add a smb:// URL for a share that doesn't allow guest logins and you'll get a cryptic "File Exists" error. It never asks for login credentials. From online searching, this is most likely due to a bug in libsmbclient where smbc_opendir will return EEXIST instead of a more appropriate error code if invalid login credentials were provided.

This was fixed in Samba 4.8:

But 18.04 is shipping 4.7.

Trying to add a share where the hostname doesn't resolve results in some cryptic messages as well, but that may or may not be a different bug.
