Steps to reproduce

1. Create a delegated directory in Crowd. Check the "nested groups" option.
2. Save the directory
3. The information is persisted as two complementary attributes in the database:

   INSERT INTO cwd_directory_attribute VALUES(32771,'false','ldap.nestedgroups.disabled')
   INSERT INTO cwd_directory_attribute VALUES(32771,'true','useNestedGroups')
   

Note that Internal Directories use just "useNestedGroups" (but not "ldap.nestedgroups.disabled") and LDAP connectors use just "ldap.nestedgroups.disabled" (but not "useNestedGroups"). In Crowd, Delegated Directories are using both.

Note as well that creating a Delegating Directory in Embedded Crowd uses just "ldap.nestedgroups.disabled", but not "useNestedGroups".
