Hello Samba list, Currently we have AD member servers that find UNIX user uid and gid via LDAP With the requirement to run winbind on member servers on newer versions of Samba I suppose this should still work with idmap backend 'nss' But we are planning to move to using AD for our UNIX info The corp assigns UNIX uids We have a corp AD realm (if that is the right word) which is say X.com and then two sites, A.X.com and B.X.com So if we use idmap backend 'ad' we must use the same range for each of A.X.com and B.X.com since the uid for users of both sites are unique but interspersed This seems to be allowed and works for tests but it does note this overlap in the logs - is this a concern? There are users in B.X.com that access shares in A.X.com We do run sssd on the Linux member servers too (for the LDAP currently), but when we move to AD should this be disabled on member servers?
