I'm having strange issues with removing one of my freeIPA masters, I managed to mess up the deletion process and my system seems to be stuck in a state of limbo, my current setup is 3 servers ( 1 has been decommissioned) that all share the CA/Domain responsibilities. When i run the command .

ipa-replica-manage list

it produces 3 servers as active masters, when this is not true as i have uninstalled ipa-server on one. Trying to delete it through that command has given me no luck, even using --force and --cleanup does not work. the same error output appears:

oxygen.eggvfx.ie: server not found

I'm not very good with ldap tools but after running 

ldapsearch -x 

there is a reference to the oxygen server still sitting in there, it seems that the dirty entry is still hanging around my system, i'm wondering if there is any way to resolve this? 

ldapsearch output:
defaultServerList: oxygen.eggvfx.ie nitrogen.eggvfx.ie lithium.eggvfx.ie

Looking at the topology graph in the web ui i can see that there are still ties between one of my servers and oxygen. It will also not allow me to delete the server ties ( error: Server is unwilling to perform: Removal of Segment disconnects topology.Deletion not allowed.) nor will the ui allow me to delete the IPA server (oxygen.eggvfx.ie: server not found) 

Any help is greatly appreciated,

Many Thanks,
