i cannot add a new user and some users try to login and get the ..
Login process failed!
Can't create user, error code: DuplicateUserName
i have completed the actions in this post with no help.
If you have multiple portals, then it can be that a Username already esists in one of the other portals and you get this error.
(unless you fill out all the details exacly the same, in that case the same user can exists for two portals)
Also when you switch(ed) to using the email address as the Username, you need to make sure beforehand that there are no duplicate Email addresses.
