at #2017052421000545 (version 4.1-4) and at 10.200.16.30 (local test-schoolslave - version 4.2) you can add a user to a workgroup, but you cannot remove it via UMC. - mark the user "x" - press "delete from workgroup" - press "save changes" - check workgroup result: user "x" ist still there. The listener.log with loglevel 4 shows in #2017052421000545 (attached at the ticket) - going to modify group with user "x" to remove "x" - modified group ("x" no longer present) - group has now following members ("x" present again)
