Here my case
ocs server 2.6 on Centos 7 Apache PHP 5.4 mariadb 5.5
ocs agent 126.96.36.199 on windows 10
LDAP (no TLS enable) authentication used to work before. Now, when I try to login with LDAP user I get error "User not registered" . I stil can see my LDAP users in OCS user list.
How can I troubleshoot and fix it, please let me know if you need screenshots or anything else.
