When I ran the UCS installation on virtualbox and then installed owncloud the settings for AD/LDAP were already populated.
When I did the same using the ESXi image the LDAP functionality had to be installed for Owncloud, once done it seemed UCS had no user for this purpose and when trying to connect directly to my own AD users didn’t work there either.
UCS is joined to our domain and I can view users/etc from within UCS, but none of the settings populated for owncloud and I cannot get it to connect.
