+Encrypted secrets
+=================
+Attributes deemed to be sensitive are now encrypted on disk. The sensitive
+values are currently:
+ pekList
+ msDS-ExecuteScriptPassword
+ currentValue
+ dBCSPwd
+ initialAuthIncoming
+ initialAuthOutgoing
+ lmPwdHistory
+ ntPwdHistory
+ priorValue
+ supplementalCredentials
+ trustAuthIncoming
+ trustAuthOutgoing
+ unicodePwd
+ clearTextPassword
+
+This encryption is enabled by default on a new provision or join, it
+can be disabled at provision or join time with the new option
+--plaintext-secrets.
+
+However, an in-place upgrade will not encrypt the database.
+
+Once encrypted, it is not possible to do an in-place downgrade (eg to
+4.7) of the database. To obtain an unencrypted copy of the database a
+new DC join should be performed, specifying the --plaintext-secrets
+option.
+
+The key file "encrypted_secrets.key" is created in the same directory
+as the database and should NEVER be disclosed. It is included by the
+samba_backup script.
