SMB using LDAP will not start when restoring a configuration on new system

      Description

      In preparation to moving to new hardware with new boot media, I backed up the configuration of a working system and selected the option to save the passwords/secrets.  After I restored the configuration on the new hardware, SMB would not start and the following was recorded in samba4/log.smbd

        smbd version 4.10.13 started.

        pdb backend ldapsam:"ldap://xxx.xxx.xxx:389" did not correctly init (error was NT_STATUS_NO_MEMORY)

      The SMB service was working correctly on the original hardware.  Entering the password in the web interface via "Directory Services/LDAP" did not resolve the problem.  There did not appear to be any other way to set the password via the web interface.  I was able to fix the problem in the shell via the command:

      smbpasswd -w bind_pw

      It appears that the configuration backup/restore does not save and/or restore the LDAP bind password in secrets.tdb.
