Background: We are migrating from our NT4 domain, to a new Windows2003 Active Directory domain, so our Linux samba server is joined the the NT4 domain where most the users live. But we are now starting to migrate (Using MS built in Migration tool) users from the NT4 domain to the Active Directory. Once the users are migrated they are not able to access shares on samba 3 file server The samba 3 box is joined to an NT4 domain. Using winbind. That NT4 domain has a trust with a Active Directory domain. Since the accounts have been migrated from the NT4 domain to the new Active Directory domain their NT4 domain account and Active Directory account share the same SID.. Could this be causing my problems? If so, how do I fix this?
