[Bug 1801227] [NEW] smbc_opendir returns EEXIST if login credentials are incorrect, breaking SMB shares in Kodi

[Ben A]

Public bug reported:

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:

https://github.com/samba-
team/samba/commit/7470b9b18af282a742929d3fc90f4be5520428a1

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.
