In section 10.1.2.2 we suggest that:
"Either of smbmount/smbumount or mount.cifs/umount.cifs must be installed. On Red Hat distributions, they are available in the package samba-client."
This is not true on RHEL6 - mount.cifs is found in the package cifs-utils, and the other tools are not available on this platform. We should update our documentation to reflect this.
This documentation was removed as part of bug 4614.
This seems to be completely removed now!
