per bug 11148
ideally, the message should indicate that SUL autocreating an account failed, rather than the generic account creation blocked message. I set the priority to trivial, but I suppose it could be enhancement too. It's not terribly important I suppose.
Suggested message:
"logging in to <project> failed. An attempt has been made to connect to this wiki with your global username <username>. This global username does not yet exist on <project>, and account creation has been blocked for your IP address <address> on <project>. Information about the block: <info>"
Version: unspecified
Severity: enhancement
