java - Grails spring security signup with moderation -

is possible in grails spring security allow signup attempts first approved moderator? if yes, can't seem figure out in docs. how do it? if no, way go it? other plugin provide feature built itself. standard prefer going spring security way. if that's not possible, have go possible.

i create user object defaults enabled false (make sure can't set enabled client):

class user {     // ...     boolean enabled = false     // .... } 

then have moderator protected view can enable users. spring security ui able part.
