rlm_ippool problem: Failed to open file - Permission denied

Hello, It's been far too long a day, and I think I'm overlooking something ridiculously simple. I get this error when starting freeradius: rlm_ippool: Failed to open file /etc/raddb/ippool.512k_high: Permission denied radiusd.conf[142]: 512k_high: Module instantiation failed. I've tried making a file called ippool.512k_high, same error. Tried chmod 777'ing it, different error: rlm_ippool: Failed to open file /etc/raddb/ippool.512k_high: Success radiusd.conf[142]: 512k_high: Module instantiation failed. Also tried chmod radiusd ippool.512k_high and chgrp. If someone could give me a helpful tip as to how to get this thing working again, I'd appreciate it a lot. Thanks all, Jan Mulders
