Check the permission of su command. It may not be executable by everybody. If it is only executable by certain group then you need to add the wanted users in the same group or make su executable by everybody .

hope this helps...

Are you using sudo on your system.
If that is the case then you should check the configuration file of sudo tool

then check /etc/sudoers for the configuration.su can be restricted using sudo.

The other option would be a group would have been created and users who require the su access can be placed in that group.

What is the permissions of the su executable
