Check_MK Werk 6455: LDAP: Multiple sync processes could be running at the same time

ID: 6455 Title: LDAP: Multiple sync processes could be running at the same time Component: Multisite Level: 1 Class: Bug fix Version: 1.6.0i1 Since 1.5.0b2 (#5986) the user synchronization is executed as background job. Because of a broken locking the sync could be executed multiple times in parallel. This issue did not lead to corrupted data, there were multiple jobs running in parallel overwriting each others results.
