I am a student at rochester institute of technology.... I am running a red hat 7 server and I was configuring my ftp server ( adding a user, changing the group, and editing the umask in .bash_profile ........ the next day I tried to execute the su command to become root remotely and I am getting ---> su: incorrect password ...... I then tried going to etc/pam.d/ and running ./su | root and get the error

bash: ./su: permission denied
bash: root: command not found

this was a trouble shooting tip I read somewhere.....
this is most interesting because this same issue is happening with my friend running a red hat 6.2 server. We think it has to do with the fact that we were changing groups around.... my friend thinks it is a security mechanism that red hat performs when doing such modifications. From what we have read we found it may have something to do with "wheels" file??? I'm not sure what that does, I think it is some sort of config file for the root passwd.......

please help, there is little to no documentation to this issue.... help please.
