We are experiencing an odd issue this morning. We have a user at one of our remote offices, he is able to log in and authenticate to openfire via Spark, however none of his default groups appear. When I open up the Admin console and check the user lists, his icon indicates that he is signed on, however when I check the details of the group that he belongs to, it appears as if he is signed off. This is happening for all users at this location, I was able to replicate it by remoting in to his PC and signing on as myself. I reinstalled the client, and restarted the openfire service to no avail. I also disabled anonymous login thinking that may have been part of the problem.
