[CentOS] can't find ldapseaerch

hello list

I'm having a very strange problem with my centos 5.5 system. For some
strange reason, this machine cannot find ldapsearch:

[root at VIRTCENT13 ~]# ldapsearch
ldapsearch: Command not found.


[root at VIRTCENT13 ~]# whereis ldapsearch
ldapsearch: /usr/bin/ldapsearch /usr/share/man/man1/ldapsearch.1.gz

ldapsearch currently lives at /usr/bin along with a lot of other
really very useful tools.


/usr/bin is also _clearly_ on my root path:i

[root at VIRTCENT13 ~]# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin

And here are the permissions and modes for this tool:

[root at VIRTCENT13 bin]# ls -l ldapsearch
-rwxr-xr-x 1 root wheel 65336 Aug 11 09:20 ldapsearch

And other things in this directory (like yum for example) work just fine:

[root at VIRTCENT13 bin]# yum repolist
Loaded plugins: fastestmirror, priorities
Existing lock /var/run/yum.pid: another copy is running as pid 11750.
Another app is currently holding the yum lock; waiting for it to exit...
  The other application is: yum-updatesd-he

    State  : Running, pid: 11750


If you feed the command line the full path to ldapsearch it works as
intended. I was wondering if anyone had any idea why ldapsearch isn't
being found?

thanks!
