If you use the "import patrons" tool to upload a CSV file of patron records it is possible to create more than one patron with the same userid. This should not be possible.

I've confirmed that it's no longer possible to import duped useres, however the import tool now dies in some conditions see bug 15840 for details -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
