Hi, I'm testing to migrate samba 3 to samba 4 AD, and after execute check duplciates appears that some users and groups have sambaSID duplciates. I have found that this users or groups, has correct entry user or group and also an entry to ou=Idmap, and I'm not sure what I have to do... this samba 3 was migrated from nt domain, and I'm not sure, but I think that this was generated with nt domain... I can't delete all entrys in ou=Idmap? what is this? What is the best practices in this situation? Thanks
