from [1]:

Other groups which have no associated user:

      * adm: Group adm is used for system monitoring tasks. Members of
        this group can read many log files in /var/log, and can use
        xconsole. Historically, /var/log was /usr/adm (and
        later /var/adm), thus the name of the group.
