[//]: # (werk v2) # Fix CME specific validations on host and folder actions key | value ---------- | --- date | 2024-10-17T05:43:28+00:00 version | 2.3.0p19 class | fix edition | cme component | wato level | 1 compatible | no CME specific validation to enforce the consistency of customer sites in a folder hierarchy were not executed properly during the following actions since 2.3.0: * Create host * Create subfolder * Edit folder * Move host * Move folder Those validations ensure that a lower level of the folder hierarchy (host or folder) can not have a site assigned which is owned by a different customer than the levels above. Due to the missing validation in previous 2.3 releases, it might have happened that unintended configuration changes were made to the configuration. Such possible inconsistencies need to be cleaned up manually.
