17944	Unable to access to User record in the admin if the user has a unmanageable password	Stefano Apostolico	Claude Paroz	"If the user has a unmanageable password (ie no hashers found) ReadOnlyPasswordHashWidget reraise  ValueError up to the UI, this prevents to access to the user record if the form contains ReadOnlyPasswordHashWidget ( admin ), this happen also for blank password. If the system use a custom backend with external authentication there is no reason for django to known the password algorithm, but should be still possible to access to the user record.
The patch simply surround the involved lined into the ReadOnlyPasswordHashWidget.render() and display a 'Unknown password hashing algorithm' message instead.
Not sure if the message could be improved/changed. "	Bug	closed	contrib.auth	1.4-rc-2	Release blocker	fixed			Accepted	0	0	0	0	0	0
