| Doc Text: |
When the smbk5pwd overlay was enabled in an OpenLDAP server, and a user changed their password, the Microsoft NT LAN Manager (NTLM) and Microsoft LAN Manager (LM) hashes were not computed correctly. This led to the sambaLMPassword and sambaNTPassword attributes being updated with incorrect values, preventing the user logging in using a Windows-based client or a Samba client.
With this update, the smbk5pwd overlay is linked against OpenSSL. As such, the NTLM and LM hashes are computed correctly, and password changes work as expected when using smbk5pwd.

New Contents:
- openldap-server with smbk5pwd overlay enabled, user performs password change
- NTLM and LM hashes are not computed, uninitialized memory is used instead, sambaLMPassword and sambaNTPasswords attributes are updated with incorrect values
- smbk5pwd module is now linked to OpenSSL library
- NTLM and LM hashes are computed correctly from the new password being set, sambaLMPassword and sambaNTPasswords attributes are updated correctly
