Mounting a native Windows CIFS share on a RHEL based Linux system requires the additional cifs-utils package be installed. Once cifs-utils is installed CIFS shares can be mounted with AD credentials. You will need to specify the mount type as cifs, the AD credentials to use to authenticate to the share, and the local Linux account to map permissions to.
