LDAP Groups

Hello, I want to control access to certain pages of my local xwiki (9.840) based on LDAP group that he/she belongs to. [I have already set up my xwiki to use my company's LDAP for authentication] How do I specify that in the rights editor? For example, if my LDAP group name is say, "abc-xyz", what string should I add in the rights editor? Option A) XWiki.abc-xyz Option B) abc-xyz ....etc Option C) Not possible with 9.840? Any others?
