LDAP authentication with local users database?

   Recently I've set up a Jabber server by using Openfire 3.6.0 for internal use. When I use LDAP for authentication, it looks like I can only use user information from LDAP server, but on our LDAP server there is no group information for each user, that makes us some headache of grouping people. The only way I can find to solve the problem is let every user to add their friends into their locat friend list which will take a lot of time.............
   So is there any way to use LDAP authentication with local group information?
   Any suggestion/help is appreciated. Thanks.

in your system properties change the provider.group.className property to be:

org.jivesoftware.openfire.group.DefaultGroupProvider

Thanks Todd, now I can create local groups to manage users, cool.
