[xwiki-users] Xwiki 2.2.3

Hello Everyone- I have two basic requests that I need help on. I have installed xwiki (war file) on Jboss app server and made LDAP authentication for editing purposes. (1) How can I add additional layer of security for certain pages only for a specific LDAP sub-group (security group). (2) What do I need to do to have the capability of importing MS Office documents directly into Xwiki. It is error out stating Open Office Plug-in server is not running. I do have Open Office installed and updated the config file. Greatly appreciate the help!
