.SH "DESCRIPTION"

This tool is part of the

\fBsamba\fR(8)
|
|
suite\&.
|
|
.PP
|
|
The format of the Samba Active Directory (AD) database changed in version 4\&.8 and 4\&.11\&. When downgrading a Samba AD Domain Controller (DC) to a release that is older than either of these versions (e\&.g\&. 4\&.11 to 4\&.10), the AD database must be manually downgraded
|
|
\fIbefore\fR
|
|
the Samba packages can be safely downgraded\&.
|
|
.PP
|
|
This tool downgrades a Samba sam\&.ldb database from the format used in version 4\&.11\&.6 to that of version 4\&.7\&. The v4\&.7 database format can safely be read by any version of Samba\&. If necessary, later versions of Samba will repack and reconfigure a v4\&.7\-format database when the samba executable is first started\&.
|
|
.PP
|
|
Note that all Samba services must be stopped on the DC before running this tool\&. Once the tool has run, do not restart samba or modify the database before the Samba software package has been downgraded\&.
