Modify ACL's on a file in Sharepoint server via web services

Is there a way to do either of the following :

1) Transfer an ACL entry on a file that is transferred to a Sharepoint server using the CopyIntoItems.asmx webservice in the Copy object?

OR

2) Access a file/document in a Sharepoint List and add an ACL entry?

I am using the CopyIntoItems.asmx webservice to migrate a file into a Sharepoint Server, but it is not migrating an file-level ACL开发者_JS百科 with it to the Sharepoint server. e.g. domain\user (Read Only) access does not get transferred to the Sharepoint server.

I understand that Sharepoint mainly works with Sharepoint level permissions, but I want to know if there is a way to do what I described with administrator access to the sharepoint server

Thanks ahead of time!

That's because SharePoint does not 'know' your ACL's, it has it's own Security mechanism, SharePoint Groups, which in turn hold for instance an AD security group / user(s). The OOTB web servics do not allow for item level secuirty operations.

You would have to write your own code / webservice and deploy that to the sharepoint server, follow the link in the answer to this question for more info on how to perform security operations on list items:
