Hello Andrew, below is the answer to your question.
For Windows Vista/Windows Server 2008 or later:
RODC forwards the "Kerberos change password " request to a writable domain \
controller, where the write actually takes place.
For Windows XP, Windows Server 2003, or Microsoft Windows 2000:
Clients locate a writable domain controller to perform the "Kerberos change password \
". RODC has no knowledge of the password change and does not immediately attempt to \
perform an RSO operation to get the new password. The RODC acquires the passwords for \
cacheable users when they log on at the RODC.
For more details on various Types of password change operations please review the \
following article. https://technet.microsoft.com/en-us/library/cc754218(v=ws.10).aspx#BKMK_PWD
Question:
Is it expected that RODC should be able to proxy Kerberos change password to the \
RWDC? Which change password is proxied from RODC to PDC?
Currently, Samba does proxy authentication, realm trust requests, but are not proxing \
any password change.
Regards,
Sreekanth Nadendla
