LDAP authenticator does not create groups but it assign users to them,
and when I say it does not create groups it just means it specifically
avoid adding users to not existing groups since technically an empty
group does not really exists. A groups is a wiki page containg objects
of class XWiki.XWikiGroups each object representing a member (a user
or a sub-group).
Look at XWikiLDAPAuthServiceImpl#addUserToXWikiGroup to see exactly
what means adding a user in a group. If you want to check if a user is
in a group simply look if this group's document contains the member
object for this user object.
