Three possible viable approaches:
1) TDB conversion approach. Read in TDB dump out LDIF (one-way)
- - samr.ldb: from tdbsam/smbpasswd, account_policy.tdb, secrets.tdb, group_mapping.tdb, idmap.tdb, privilege.tdb
+ - samr.ldb: from tdbsam/smbpasswd, account_policy.tdb, secrets.tdb, group_mapping.tdb, privilege.tdb
- registry.ldb: from registry.tdb
- wins.ldif: from wins.tdb/wins.dat
- smb.conf/ea's: generated from the old smb.conf + share_info.tdb
+ - winbind.ldif: from winbindd_idmap.tdb (custom file format, not used
+ by samba4 yet as it doesn't
+ have Winbind yet)
(one-way upgrades can be done by using ldbsearch -a on these dynamically
generated ldb's)
