we just made an upgrade from owncloud v9.09 to v9.1.5. owncloud-authentication is based on ldap. Our ldap-server is a samba4-server, which simulates an AD.
owncloud is very very slow, but the owncloud-server itself has actually nothing to do (no cpu load, no ram using). The problem is, that owncloud causes a 100% cpu-load on the ldap-server and this with less than 10 users being active. So a ldap-user needs minutes only to login, on the contrary a local owncloud-user needs just some seconds.
can it be that the "ldap-backend"-app has a problem ? I'm thinking this, because with our new version we are not able to delete ldap-users from owncloud anymore - users, who dont exist in ldap anymore but still in the owncloud-db. the occ-tool says " is not a valid user anymore".
why this cpu-load on the ldap-server ? what is owncloud doing ?
We really need help as quick as possible, because right now owncloud is not usable.
thanks in advance
