I have a problem with the FBA solution, when I create new external users it works fine, and the full name and email address are correctly displayed. Five minutes after that it updates the user and deletes the email address and Full name, I don't know why.
Our solutions requires both fields to be completed since the next process requires to notify the users.
The solution worked fine for a couple of weeks, then this problem appeared. I was using FBA 1.3.1 and then upgrade to 1.3.5 and the problem is still there.
I will update with any future details. Any help or comments are welcome.
