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 👍

研究方向
Investigate the DRSUAPI error code 0x20e4 (ERROR DS CANT FIND EXPECTED NC) in the context of Samba AD DC. Check the secretsdump.py implementation in the impacket repository, specifically the DRSUAPI method. Compare with working configurations of Samba and ensure the correct naming context is being queried. Consider asking the issue author for their Samba configuration and domain structure. Look for any related issues or pull requests that might address this.
