https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=13655 --- Comment #1 from Katrin Fischer <katrin.fischer@bsz-bw.de> --- Koha should automatically generate a valid username on saving the patron. For organisations this currently fails and you are forced to manually enter a username. To test: - Add a new patron of a patron category marked as 'organisation'. - Enter a name and cardnumber for the patron and try to save. - You will see an error message: The following fields are wrong. Please fix them. Username/password already exists. - Verify you can only save the patron after manually entering a userid. -- You are receiving this mail because: You are watching all bug changes.
