Active Directory Integration - clear-text password used



I already read this document - https://www.paessler.com/manuals/prtg/active_directory_integration.htm - and the integration is working. But the password for the authentication is send as clear-text password. This is not really secure. Is there any way for a secure authentication with encrypted passwords? Or do you have something like Kerberos authentication on the roadmap?

PRTG uses the 'ADSI Interface' for all requests to the Active Directory. For the security level of the connection the 'ADS_SECURE_AUTHENTICATION'-Flag is set / used to be exact. To which the MSDN states:
"Requests secure authentication. When this flag is set, the WinNT provider uses NT LAN Manager (NTLM) to authenticate the client. Active Directory will use Kerberos, and possibly NTLM, to authenticate the client."
Can you provide more details on this? Where did you find plain text password transmission? And which PRTG version are you using?

best regards.
