function ldapgroups_roles_filter() is enabled by default

Hello,

I've just spent quite a bit of time figuring out why my LDAP group->role stuff wasn't working as I expected. I found out it was because ldapgroups_roles_filter() is enabled by default.

Comment before the function in ldap_integration/ldapgroups.conf.php:

Note: Uncommenting this function will limit the groups -> roles conversion to ONLY those groups that are specified in the function.

IMHO this should not be uncommented by default *OR* the UI should provide a big message about it.

Thanks a lot for a group module, now that I've got this commented out it's working like a dream. A massive improvement over early versions!
