Need to restrict the close of catalog task

[vinuth v]

Hi All,

Query 

1) Only the ITIL user who is part of the assignment group can close the catalog Task. (Admins are allowed)
2) Persons who are not part of groups are restricted to close the catalog task.
3) Requester who has raised the request are allowed to close the catalog task

Please any one provide me the input,

Thanks in advance,

Vinuth
