In this position paper we highlight issues concerning management of authorisation in coalitions. We identify two main issues related to the administration of authorisations in dynamic coalitions. The first issue concerns /decentralisation of administration/, and we show how an existing framework developed at SICS addresses this issue. The second issue concerns /decentralisation of enforcement/ of authorisation and we describe a new approach to address this issue by extending the current access control models with the notion of entitlement. The idea is that both authorisations and entitlements are specified in access contracts that coalition partners agree upon. These contracts can be used for automating access decision making by those controlling access to coalition resources.
