Steps to reproduce
- use external users
- use vsftpd
- use self signed certs
Expected behaviour
Would work
Actual behaviour
I see this in logs:

Server configuration
Operating system: Centos 7
Web server: Apache
Database: mariadb
PHP version: 7
ownCloud version: 9.1.5
Updated from an older ownCloud or fresh install:
Where did you install ownCloud from:
Signing status (ownCloud 9.0 and above):
Login as admin user into your ownCloud and access
http://example.com/index.php/settings/integrity/failed
paste the results into https://gist.github.com/ and puth the link here.The content of config/config.php:
...
'user_backends' => array (
0 => array (
'class' => 'OC_User_FTP',
'arguments' => array (
0 => 'localhost:990',
1 => 'true',
2 => array ( 'allow_self_signed' => true, ),
),
),
..
Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.
or
If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder
*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.List of activated apps:
If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.Are you using external storage, if yes which one: local/smb/sftp/...
Are you using encryption: yes/no
Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...
LDAP configuration (delete this part if not used)
With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder
Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';
Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.Client configuration

Logs
Web server error log
Insert your webserver log hereownCloud log (data/owncloud.log)
Insert your ownCloud log hereBrowser log
Insert your browser log here, this could for example include:
a) The javascript console log
b) The network log
c) ...Strange thing, to me, is that from owncloud.log:
...
Peer certificate CN=sucker.localdomain' did not match expected CN=localhost' at ..
...
Where does owncloud get CNR=localhost from?
Both Apache & vsftpd point/use the same self signed certificates.
Would you know what might be a problem?
many thanks, L.
