Hi, Currently I have an issue with a radius servers, every day the user authentication appears to not work for our Eduroam WIFI, after restarting the server everything begins to work again. I am currently using SAMBA to connect FreeRADIUS to Active Directory. Please see the errors below, any advice would be appreciated [root@EKCRadius5 /usr/home/netsys]# su freeradius $ /usr/local/bin/ntlm_auth --request-nt-key --domain=EASTKENT --username=service.freeradius --password=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx NT_STATUS_FILE_LOCK_CONFLICT: A requested read/write cannot be granted due to a conflicting file lock.
