Multilib version problems found pam.i686

[sworton]

Hi - I'm after some help around a Linux forwarder I'm trying to configure to handle OPSEC LEA connectivity for Checkpoint logs from a smart-1 appliance.

We're using Red Hat Enterprise Linux Server release 7.3 and I'm getting this error.

External handler failed with code '1' and output: 'REST ERROR[400]: Bad Request - GNU C library (glibc.i686 32-bit and pam.i686) is missing.

when I check the libraries I get this:

[root@end-ipmc76 ~]# yum install glibc.i686
Loaded plugins: product-id, search-disabled-repos, subscription-manager
Package glibc-2.17-222.el7.i686 already installed and latest version
Nothing to do

[root@end-ipmc76 ~]# yum install pam.i686

Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

  1. You have an upgrade for pam which is missing some
        dependency that another package requires. Yum is trying to
        solve this by installing an older version of pam of the
        different architecture. If you exclude the bad architecture
        yum will tell you what the root cause is (which package
        requires what). You can try redoing the upgrade with
        --exclude pam.otherarch ... this should give you an error
        message showing the root cause of the problem.
     2. You have multiple architectures of pam installed, but
        yum can only see an upgrade for one of those architectures.
        If you don't want/need both architectures anymore then you
        can remove the one with the missing update and everything
        will work.
     3. You have duplicate versions of pam installed already.
        You can use "yum check" to get yum show these errors.
   ...you can also use --setopt=protected_multilib=false to remove
   this checking, however this is almost never the correct thing to
   do as something else is very likely to go wrong (often causing
   much more problems).
   Protected multilib versions: pam-1.1.8-22.el7.i686 != pam-1.1.8-18.el7.x86_64

yum check just came back with this

[root@end-ipmc76 ~]# yum check
Loaded plugins: product-id, search-disabled-repos, subscription-manager
check all

I'm not really sure what to do next?

Thanks for any help.
