[Samba] Adding a new DC - ID Mappings

[Rob Mason]

I’m looking to replace a DC within a small network by adding a new DC and transferring FMSO roles, then demoting the old DC (https://wiki.samba.org/index.php/Demoting_a_Samba_AD_DC).

I am able to successfully deploy the new DC following directions in https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory. However, I am struggling with ID mappings – I’m not really understanding how this should work. Should I have to manually re-create the passwd/group entries on my new DC in order to gain the old uid/gid values?  I’ve copied the idmap.ldb as suggested in the text, and whilst wbinfo returns the domain users, getent doesn’t show the domain accounts, only the local passwd entries.

Have I missed something obvious??

thanks
