** Description changed:
+ [Impact]
+
+ A regression in Samba causes the wrong error message to be returned on
+ an unsuccessful login, returning EEXIST instead of EACCESS or EPERM.
+
+ [Tese Case]

+ echo -e "\nPoint your file browser to smb://$(ip addr | grep 'state UP' -A2 |
tail -n1 | awk '{print $2}' | cut -f1 -d'/')/test and connect as guest"
+
+ * Connect to the smb:// address provided using a file browser, logging in as
an anonymous guest. You'll see an error to the effect of "file exists"
+ * Note: smbclient doesn't exhibit the incorrect behavior (smbclient
//localhost/test -U guest -N)

+
+ [Regression Potential]
+
+ The change reverts a regression in the closing order in certain cases
+ from a previous version of samba, and should not cause further

+ Bug Description
+
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.
