While configuring the appliance on [..]/login/login you can set a security provider. If you edit the local setting and choose a standard profile which you want to apply to any user you lock yourself out of the configuration panel including all admins accounts even the "admin" account. This setting is accepted without a special warning. So even an admin cannot take this back but only support with tier 3 help! Incident #: 510327 - Please correct that so at least there is a special waring and the "admin" account still has access.
