Re: [Samba] Organization of Users in Samba4
Hi Andrew, you can create the user in another OU if you want: samba-tool user add User3 passw3rd --userou=OrgUnit --userou=USEROU Alternative location (without domainDN counterpart) to default CN=Users in which new user object will be created Regards, Christian -Ursprüngliche Nachricht- Von: samba-boun...@lists.samba.org [mailto:samba-boun...@lists.samba.org] Im Auftrag von Andrew Martin Gesendet: Donnerstag, 24. Januar 2013 00:21 An: samba@lists.samba.org Betreff: [Samba] Organization of Users in Samba4 Hello, I am working on migrating from OpenLDAP using the inetOrgPerson schema to Samba4. I would like to continue to provide backwards compatibility with our existing authentication service. In OpenLDAP, users are all contained inside the People organizational unit and referenced by uid, for example: dn: uid=myuser,ou=People,dc=example,dc=com When using samba-tool to add a user, it places the user inside of the Users cn, and references the user via its cn entry rather than via uid: dn: cn=myuser,cn=Users,dc=example,dc=com Is there any Samba4 or AD reason why I need to use cn=myuser,cn=Users,dc=example,dc=com for users, or can I import them to uid=username,ou=People,dc=example,dc=com and use this organizational structure instead?
