Error Summary
-------------

Maybe you should remove the 32bit version of openldap (openldap-2.4.19-15.el6.i686) and then try again.

first you really do not want to manually do that LONG list
use a groupinstall

that will install what is needed


long lists like what you posted will most of the time cause conflicts
It is best to avoid doing that .

Also GET OUT OF THE HABIT NOW before you DO make a habit out of it
DO NOT use the "-y" option unless you ARE 100% SURE of 100% of what is going to happen

that "yes to all" is VERY powerful and you can NOT stop it once it starts


also what repos are installed
some are INCOMPATIBLE with others
http://wiki.centos.org/AdditionalResources/Repositories

install AND configure yum-Priorities plugin
and heed ALL warnings


the error is a conflict between the 32 bit AND 64 bit versions and ALSO different versions of "openldap"

uninstall the old version that is the 32 bit and install the newer 64 bit

su -
yum remove openldap-2.4.19-15.el6.i686[/code]
pay VERY close attention to the output to see if 1/2 of the OS wants to come with it
if not then hit "y" for yes
