Joining Linux host to Windows AD is widely documented.However I struggle to find any guides or best practices on how to join Linux clones that were already members of the domain.
Naturally things start to break due to the identical SIDs .I cannot use 'net ads unjoin' as this would remove original SID from the domain...
This should answer your question:
Active directory with duplicate machine SIDs
Duplicate SIDs don't matter (for non domain controllers.)
edit: To clarify - each machine will be given a new RID as it is joined to the domain, regardless of what its local SID is. A RID will never be re-used, ever, regardless of the member server being a clone.
