Add an entry in the tree view ; the entry is added in the children array of its parent
The added entry is created using the factory class defined in $_SESSION[APPCONFIG]->custom->appearance['entry_factory']
Parameters:
This function will take the DN, convert it to lowercase and strip unnessary commas. This result will be used as the index for the tree object.
Any display of a DN should use the object->dn entry, not the index. The reason we need to do this is because: uid=User A,ou=People,c=AU and uid=User B, ou=PeOpLe, c=au are infact in the same branch, but PLA will show them inconsistently.
Parameters:
