It looks like the latest kernel release fixes this issue:
CentOS pushed the kernel update last night (CEBA-2015:1827 CentOS 6 kernel
BugFix Update). I've tested it on a machine that logged the error every
time we ran a certain cron job, and so far the errors are no longer
appearing.
From the RedHat advisory at
https://rhn.redhat.com/errata/RHBA-2015-1827.html :
* When logging in as a user and trying to mount a share using the "cd"
command,
the UID and GID autofs additional variables previously took incorrect
values,
taking root UID and GID instead of user's UID and GID. The bug in the
assignment
of uid and gid mount requests has been fixed, and UID and GID now get the
correct values with autofs configuration on Red Hat Enterprise Linux 6.7.
