Bug 1649434

.The `samba` packages have been to version 4.9.1 The `samba` packages have been upgraded to upstream version 4.9.1, which provides a number of bug fixes and enhancements over the previous version. The most notable changes include: * The Clustered Trivial Database (CTDB) configuration has been changed completely. Administrators must now specify parameters for the `ctdb` service and corresponding utilities in the `/etc/ctdb/ctdb.conf` file in a format similar to the Samba configuration. For further details, see the `ctdb.conf(5)` man page. Use the `/usr/share/doc/ctdb/examples/config_migrate.sh` script to migrate the current configuration. * The default values of the following parameters in the `/etc/samba/smb.conf` file have been changed as follows: ** `map readonly`: `no` ** `store dos attributes`: `yes` ** `ea support`: `yes` ** `full_audit:success`: Not set ** `full_audit:failure`: Not set * The `net ads setspn` command has been added for managing Windows Service Principal Names (SPN) on Active Directory (AD). This command provides the same basic functionality as the `setspn.exe` utility on Windows. For example, administrators can use it to add, delete, and list Windows SPNs stored in an AD computer object. * The `net ads keytab add` command no longer attempts to convert the service class passed to the command into a Windows SPN, which is then added to the AD computer object. By default, the command now only updates the keytab file. The new `net ads add_update_ads` command has been added to preserve the previous behavior. However, administrators should use the new `net ads setspn add` command instead. Samba automatically updates its tdb database files when the "smbd", "nmbd", or "winbind" daemon starts. Back up the databases files before starting Samba. Note that Red Hat does not support downgrading tdb database files.
