Release : 14.2, 14.3
Component : CA IDENTITY SUITE (VIRTUAL APPLIANCE)
This is a known issue.
Please, to workaround this issue do these following steps:
1) Make sure you have a xml export as backup of task "IMRCM Create Active Directory Group". You will need this backup to restore this task after next steps.
2) Go to "Roles and Tasks" -> "Delete Admin Task" -> Search by "IMRCM Create Active Directory Group" and delete it.
3) Test again Endpoints -> "Manage Endpoint Groups" -> "Create Endpoint Group" for MS AD. At this point should work.
4) Import backup the backup you did in step 1 of xml export for "IMRCM Create Active Directory Group" and test again that should keep working.
This problem was already fixed in the IM 14.4 CP1 CHF2 and later as mentioned in the list of fixes so I suggest upgrading to the latest 14.4 CP2 as you would benefit from this fix and other fixes.

Unable to create an Active Directory Group from Identity Manager. For provisioning operations, the Identity Manager framework delegates an action/operation to the endpoint dispatching task via an admin task. The lookup operation for selecting the dispatching task does not work as expected.
