What steps will reproduce the problem? 1. Enable mod_register. 2. Use a client supporting IBR. 3. Create an account containing an uppercase letter, like Test@your-domain.tld What is the expected output? What do you see instead? The account test@your-domain.tld should have been created. Instead a not-acceptable error has been sent and no account has been created. What version of the product are you using? On what operating system? hg:bdaff978c790 (0.10) on ArchLinux current. Please provide any additional information below. The issue is most likely that stringprep hasn’t been applied on the requested <username/>.

Oh hmm, now I get an error of type wait, so it might be that I did too many attempts at creating an account and am now blacklisted by my server, I haven’t checked what it was before: <iq id='b54f9de7-79fc-4231-8884-49837a6ac41f' type='error' from='im.apinc.org'><error type='wait'><not-acceptable xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error></iq>

Actually no, the throttle check seem to erroneously trigger with an uppercase letter, since I was able to register the same account in lowercase.

Oh, the throttle check was inverted. https://hg.prosody.im/0.10/rev/c61ea328fac2
