Support for flattening LDAP nested groups
Nested / complex / hierarchic groups as defined in LDAP are flattened. This means: if
group A is member of group B, the members of group A will also be
members of group B.
Cyclic paths are detected and followed only once.
The features is disable by default.
Set property "ldap.flattenNestedGroups" to "true" to enable it.
