I recently deployed a MIM2016/FIM dev environment. My test users seem to be working fine in the parent domain, but users in the child domain are getting unauthorized errors at the pw registration screen. When I look at users on the MIM portal I see all my test users in the parent and child domains. The domain listed for the child domain users is the parent domain instead of the child domain. If I click on one of the users I am unable to change the domain manually because only the parent domain is listed in the domain drop down window. My sync service manager is pointing to the child domain and OU and syncs with one of the child domain DC's successfully. The DN and CN are correct. Just not sure why its showing the parent domain as the domain rather then the child domain. Any help would be much appreciated.
***Update*** So it seems if I manually go into advanced view > Extended Attributes > Domain and type in the child domain it works. Im not sure why it isn't automatically assigned the child domain though.
