Hello. I'm trying to update their samba3.6 to the new version. Use the instructions https://wiki.samba.org/index.php/Samba4/samba-tool/domain/classicupgrade/HOWTO Just use the latest build of sernet. My samba3.6 work is not in the role AD, and as a standart file server with LDAP Backend, which stores users and groups. I'm trying to take advantage of the update utility. But getting error. samba-tool domain classicupgrade --dbdir=/var/lib/samba/samba3 --use-xattrs=yes --realm=SAMBA4.SERVDESK.RU/var/lib/samba/samba3/smb.conf --testparm=/usr/bin/testparm both dbdir and testparm specified, ignoring dbdir.
