Hi,
Yesterday the following package updates were applied to our main RHEL5 FreeRADIUS server after which it was successfully rebooted:
since that version of SAMBA is generally sane...and CentOS 5 is old (I'm surprised there are still updates....) sounds like winbind_privileged issues....you can either change group of that directory (contains the pipe file) to eg radiusd (to match group of your radiusd process) , or add radiusd user to the wbpriv group ...as , naughty naughty, installation of samba adjusts file permissions set by an admin in the post-install phase (bad RH people.....). /var/lib/samba for the winbindd_privileged directory PS move to 3.1.x on CentOS7 with SAMBA 4.3 install - you can then use native winbind connections and avoid this ntlm_auth issue alan
