ClassCastException on setup-ldap-user.jsp DefaultUserProvider cannot be cast to LdapUserProvider


I am having an issue with a new OpenFire that we are creating. The server that we are installing OpenFire 4.0.3 is a Windows 2012 server VM within VMware 5.5. We are doing a LDAP/Active Directory set up with our environment. We have been able to go through most of the OpenFire configuration but we run into a hang up after the 'Users Settings' connection back to our AD environment. We are able to "test settings" because it sees our users within AD. Below is what we see before getting to the next last step.

I can see how it might be still valid; not sure of the exact conditions to trigger it (couldn't find the steps myself) but there's certainly an unprotected cast that could be handled better. I'll see if I can get to that in the next day or so.

Hi Greg,

Could you kindly review this issue to see if it is still valid?
