This is a known issue that is scheduled to be fixed very soon. The current admin console uses REST calls which hard-code the credentials to the default values. When the default is changed, it does not pass the correct information.
As for logging in with "adminadmin"... that's the old default password, try using a blank (empty) password now with asadmin login.
Both 13418 and 13419 are related to the same issue. The console does not yet work if the password(s) have been changed (or users added/removed -- all of which require credentials to be sent).
Sorry for the inconvenience... however, all these issues should be addressed soon! :)
