I've tried this about 3-4 times now and I always get stuck at the same spot. I'm in the SAMBA section of the RHCSA. At about 7:45 in the 2nd video where you connect with smbclient -U user -L <IP Address> I always get "session setup failed: NT_STATUS_LOGON_FAILURE". I have double, triple, quadruple-checked that I'm using the same password from smbpasswd -a user. Is anyone else having this issue?
