>I try I get the following error:

You have to set the TERM env var, for example:
TERM=vt220

>The first two lines in /etc/group look like this:
>   wheel:*:0:root,ola
>   users:*100:
>The first and last lines in /etc/passwd look like this:
>   root:*:0:0:Charlie &:/root:/bin/csh
>   ola:*:100:100::/home/ola:/bin/csh

The problem may be due to the absence of your group member.
You have to edit the /etc/group file as follow:
wheel:*:0:root,ola
users:*:100:ola

where 100 is the GID number and must be equal to the GID number of your
user ola in the /etc/passwd file.

Once you have set your user you can use the "su" command to login as
super user.
