Better error when LDAP fails due to missing HTTP session

Description

During the setup, the setup wizard occasionally gives an unqualified 'error' when trying to set up LDAP. No context is given, which leaves the end-user with no clue what to do.

Turns out that this happens when the HTTP session that's driving the setup wizard pages is somehow malformed (eg: missing a property).

Openfire should indicate so.
