Hi, I had an active-directory authentication based samba system up and running, working well. However, I tried to access an SMB share on the server a few days back and just get a windows login user/password prompt. I'm trying to debug why theres a "system error". PAM is configured for pam_winbind.so in /etc/pam.d/system-auth, and I can ssh into the system using a domain account. The share is set to allow all RO access, but I can't even get a share listing off the server (\\<servername>) Starting to drive me nuts... Thanks, Adrian Server:? Centos 4.5, 32bit. Client:?
