Re: Errors executing password change procedure

Users already have the ability to change their passwords, assuming they can actually login. The problem, according to the project owner, arises when they don't know their current password, it has expired, or they locked their account. They want a GUI that end_users can access to change their password in any situation. I'm told it will have checks in place to ensure they can change only their own password. Opening a ticket with the DBA team is too difficult and time consuming. Project owner's words, not mine.
