Additional context

Hi,

When trying to secretsdump.py -no-pass -just-dc Domain/'DC_NETBIOS_NAME$'@DC_IP_ADDR into my SAMBA AD DC I face an error message. I Wanted to know if it was related to the implementation of secretdump or If I could have missed something during my samba configuration.

Thanks and have a great week 👍

Research direction
Check the DRSUAPI naming context error (0x20e4) by verifying the target Samba AD DC's naming contexts and ensuring the DRSUAPI interface is correctly exposed.
