8878	Authentication in the admin should not make any assumptions on valid user names	jdetaeye	nobody	"
When the user authentication with all configured authentication backend fails, the admin application adds some additional checks when the user name contains the character @.[[BR]]

This does't make sense: the admin application can't know what is a valid user name for the backends. For some backends a @ in the user name may well be valid."		closed	contrib.admin	dev		duplicate	authentication		Unreviewed	1	0	0	0	0	0
