I doubt those 2 problems are related. For the LDAP problem, try specifying the DSC in Distinguished format (e.g. LDAP://DC=my,DC=domain,DC=com). Then try to create a distribution task and add users. If you are able to browse/add users then your DSC is working fine.
For the second problem, try the solution I posted in response to your other QlikCommunity post.
