MySQL Enterprise Backup 8.0 User's Guide  /  Using MySQL Enterprise Backup  /  Using LDAP for Server Authentication

Chapter 16 Using LDAP for Server Authentication

For MySQL Enterprise Backup 8.0.22 and later: LDAP pluggable authentication is a feature supported by the MySQL Enterprise Edition; the user by which mysqlbackup connects to the server can be authenticated using LDAP. Beyond proper setup for LDAP on the server side, the following requirements apply for LDAP authentication to work with mysqlbackup:

  • If the user is using simple LDAP authentication, the password is communicated to the server in cleartext; enable Client-Side Cleartext Pluggable Authentication by using the --enable-cleartext-plugin option in your mysqlbackup command, or set the environment variable LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN=[1|Y|y] in the environment you run the command.

  • If the user is using SASL-based LDAP authentication and the client-side plugin (authentication_ldap_sasl_client) is not located in the server's plugin folder, the --plugin-dir option should be used with the mysqlbackup command to specify the location of the plugin, or the same information should be provided by setting the environment variable LIBMYSQL_PLUGIN_DIR in the environment you run the command.

The following are some sample commands for using LDAP authentication:

Example 16.1 Backup Using Simple LDAP Authentication

mysqlbackup --user=mysqlbackup --password=password --host=127.0.0.1 \
  --backup-dir=/home/mysqlbackup/backup-tmp  --backup-image=/home/mysqlbackup/backups/my.mbi \
  --enable-cleartext-plugin backup-to-image

Example 16.2 TTS Restore Using Simple LDAP Authentication

mysqlbackup --user=mysqlbackup --password=password  --host=127.0.0.1 \
  --backup-dir=/home/mysqlbackup/backup-tmp  --backup-image=/home/mysqlbackup/backups/my.mbi \
--include-tables=REGEX --enable-cleartext-plugin copy-back-and-apply-log

Example 16.3 Backup Using SALS-based LDAP Authentication

mysqlbackup --user=mysqlbackup --password=password --host=127.0.0.1 \
  --backup-dir=/home/mysqlbackup/backup-tmp  --backup-image=/home/mysqlbackup/backups/my.mbi \
  --plugin-dir=SASL_plugin-dir backup-to-image

Example 16.4 TTS Restore Using SALS-based Authentication

mysqlbackup --user=mysqlbackup --password=password  --host=127.0.0.1 \
  --backup-dir=/home/mysqlbackup/backup-tmp  --backup-image=/home/mysqlbackup/backups/my.mbi \
--include-tables=REGEX --plugin-dir=SASL_plugin-dir copy-back-and-apply-log
