libkeyutils.so not found

[Gianluca Cecchi]

After yesterday update my x86_64 machine fails to find libkeyutils.so.1 library.
Many services such as sendmail, rpcbind, cups and sm-client complain about this

Apart from the yum update with the gui puplet the only thing I did
yesterday was to remove, without forcing nothing, some i386 packages
(only "rpm -e " command used).
I don't know if this problem depends on yum update or i386 removal.

there are other problems arised:

- yum failing to start
I tried
[root at pevit00 log]# yum install /usr/lib64/libkeyutils.so.1
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   No module named _sha256

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.5 (r25:51908, Apr 10 2007, 10:27:40)
[GCC 4.1.2 20070403 (Red Hat 4.1.2-8)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq

In yum.log I have

- Init level 5 fails to start. The screen remains at the blue circle
with black background, without arriving at gdm login screen

with ps -ef it seems that I have  the process /bin/sh /etc/gdm/Init/Default
ciclically trying to start.... see below

- before update I used intel driver in xorg.conf. now I tried both
with it and with the i810 but no difference.

I tried both latest kernel and the 3116 one but no difference

in dmesg I have these:

Any hints on what to do?
Are these three problems actually different faces of the same one
(missing of libkeyutils.so.1)?
In which package can I find the shared library... as I cannot use yum
to search..?

Thanks
