The group administrator (that is, the owner of a group) can specify a group terminal option for the group by using the ALTGROUP command with the NOTERMUACC operand. With this option, users of the group are authorized to log on to TSO only from those RACF-protected terminals to which they have been specifically authorized access by the PERMIT command. That is, users of the group might not be authorized to log on to TSO from terminals (either RACF-defined or otherwise) based on the universal access authority of the terminals.
