That looks REALLY REALLY REALLY BAD.  YOUR machine is trying to mount a 
directory from
another machine and is being refused.  If YOU didn't set this up then 
someone else on your machine did.
The name of the directory ".hidden" implies evil intent.  See if you can 
find a check root kit package for
Centos.  Lock down your machine right away and start looking for 
modified RPMs.

I don't use automount, but it doesn't look like a normal user should be 
able to touch the control files involved.
Examine /etc/auto.master, man autofs and man automount.
