Disable LDAP TLS connection

Some ownCloud users experience an issue when already switched off 'SSL certificate validation' in ownCloud Administration GUI doesn't cause changes in database.

It leads to errors in /usr/share/webapps/owncloud/data/owncloud.log:

{
"reqId":"abc1ac1020dbda66970651f039359229",
"remoteAddr":"94.127.178.121",
"app":"PHP",
"message":"ldap_start_tls(): Unable to start TLS: Connect error at \/usr\/share\/webapps\/owncloud\/apps\/user_ldap\/lib\/ldap.php#252",

}
{
"reqId":"abc1ac1020dbda66970651f039359229",

Assuming your DB name is ocdb, you can verify actual configuration stored in database with command:

(inside container):

mysql -e "select * from oc_appconfig where configkey='ldap_tls';" ocdb # OR
psql -c "select * from oc_appconfig where configkey='ldap_tls';" ocdb postgres

(outside container, assuming oc is your container name):

docker exec oc mysql -e "select * from oc_appconfig where configkey='ldap_tls';" ocdb # OR
docker exec oc psql -c "select * from oc_appconfig where configkey='ldap_tls';" ocdb postgres

To fix this issue and completely turn off SSL certificate verification, run:

(inside container):

mysql -e "update oc_appconfig set configvalue=0 where configkey='ldap_tls';" ocdb # OR
psql -c "update oc_appconfig set configvalue=0 where configkey='ldap_tls';" ocdb postgres

(outside container, assuming oc is your container name):

docker exec oc mysql -e "update oc_appconfig set configvalue=0 where configkey='ldap_tls';" ocdb # OR
docker exec oc psql -c "update oc_appconfig set configvalue=0 where configkey='ldap_tls';" ocdb postgres
