Operating system: Centos 7
Web server: httpd
PHP version: 7.2
ownCloud version: 10.1.0
Updated from an older ownCloud or fresh install: fresh install
I have an OwnCloud server in the IT infrastructure that using AD/LDAP (from Marketplace) connector for authentification. It worked perfectly for a couple months but now it’s periodically block all user accounts in domain. There are a lot of records on the Windows 2016 Server security log that contains inforamtion that failed logon attemtps from Owncloud server. I’ve checked log files in the Centos but haven’t found any errors or something. Also I use fail2ban on server and the jail is also empty.
Does anybody face up with the same problem? How to solve it?
