We have a SharePoint site using FBA with various FBA accounts on it.
Recently, once in a while (Seems to be once a week at the moment) one of the users "Full Name" gets reseted to the fba user name "i:0#.f|fbamember...". Nobody has access to this and I haven't accessed the SharePoint site either. It seems to only happen to this user too, the other are correct. I correct the Full name when it happens, but eventually will come back again.
