I just did a fresh install of Openfire 4.0.4, on a brand new server. Followed the instructions to get SSO to work, and it does! I can use SSO and get Spark to log in. However, even though the users and groups are populated from AD and appear in the admin console, they do not appear in the spark client. Even the "Offline Group" displays as empty, saying, "there are no online contacts in this group". A logged-in spark user shows as logged in at the console, and even displays presence correctly. What could be preventing the names from displaying in the Spark client (both 2.7.7. and 2.8.2)?
