Allowed in, having owned up (8)
I believe the answer is:
admitted
I believe this clue is a double definition.
'allowed in' is the first definition.
('admit' can be a synonym of 'allow in')
'owned up' is the second definition.
(I've seen this before)
'having' is the link.
(Other definitions for admitted that I've seen before include "Acknowledged to be true" , "Owned up or let in" , "Allowed to enter or owned up" , "being given access" , "Conceded; let in" .)
