Hello, Compile and install samba-4.13.17 from source. After the installation and configuration are completed, the winbind startup status shows an error, and the ntlm_auth authentication fails. Compile and install with the following command: [root at myradius samba-4.13.17]# ./configure --disable-python --without-ad-dc [root at myradius samba-4.13.17]# make && make install Now only start smb and winbind The same system version, when installed with yum, the startup status of winbind has no error prompt, but the ntlm_auth authentication also fails, and the prompt is the same as the source installation. Due to the display error of the text, please check the attachment. Sorry for the inconvenience. Looking forward to your professional guidance.
