On most modern systems, user accounts in /home are only accessible by
that user (i.e. tbeecher in your case). Are the permissions on
/home/tbeecher such that the nagios user can access the directory? I
know you said you tested it from the command line but you didn't specify
if your test was run as the nagios user.
