Hi, I'm currently working on getting our site migrated from a NT4 domain into an AD domain. 2-way trusts have been established. The idea is that with SID history users in the AD domain can access their files on the samba 3.0.22 server in the NT4 domain. This works for an unknown time interval. with the AD account I can access the shares through the sid history in the NT4 domain joined samba server. Winbind is used for user auth. Say for example my NT4 user gets mapped to the uid 10000. I access the server from my AD account which will at that stage revert to 10000 form my NT4 account. After an unknown time interval this stops working. All of a sudden my AD account for example will resolve to uid 100011 and cannot access the shares where uid 10000 has permission for. If I run a 'getent passwd' I get all users returned from winbind with the last returned uid is 10010. After the unknown time interval the AD account with SID History falls outside the range returned by winbind. If I restart the winbind and smb services together everything is working again. the AD account is once again goes through as the NT4 uid 10000. Then after a while (I really don't know the time that is passing, it's different everytime) this stops working and I end up with the AD account resolving as 100011 which falls outside the range returned by winbind. I need to restart both the smb services and the winbind service to get it working again from a short while. If I only restart smb services or the winbind service it does not work. Does anybody know what is causing this and hopefully also can fix this? If not, does anybody know how I can get the NT4 domain and the AD domain both enummerated in winbind so I can temporarily fix this by allowing AD users and groups to be assigned to shares and file permissions? for aslong as the migration will take I need both the NT4 domain and the AD domain to be able to access shares on the samba server. Many thanks in advance, Ton Hoogstraten
