"I have problems re-setting my password. Its saying that my existing password is incorrect. But that's a system generated one which now I want to change to a memorable one but gives the message as stated."
I wonder if it is something to do with the reset password email the user receives. Our users inboxes are quite sensitive, so that email could be going into spam. So they don't think it has worked, then reset it again, but might dig out the old one that was in spam, and that link would then not work.
Any help, much appreciated. Thank you.
