this is a quote from the wiki page you listed:
Uncomment the two lines indicated to enable the authentication functions:
# auth/keyfs -wp -m /mnt/keys /adm/keys >/dev/null >[2=1]
# auth/cron >>/sys/log/cron >[2=1] &
Uncomment the indicated code block. The file names indicate the port
and protocol, and the file itself contains the commands for starting a
service. The authsrv. and ! prefixes indicate disabled services;
adding or removing the prefix disables or enables the service:
# if(! test -e /rc/bin/service.auth/il566){
# mv /rc/bin/service.auth/authsrv.il566 /rc/bin/service.auth/il566
# mv /rc/bin/service.auth/authsrv.tcp567 /rc/bin/service.auth/tcp567
# mv /rc/bin/service/il566 /rc/bin/service/!il566
# mv /rc/bin/service/tcp567 /rc/bin/service/!tcp567
# }
The original /rc/bin/service/il566 and /rc/bin/service/tcp567 services
were proxy calls for the authentication services to be used by
terminals. We don't need these on the authentication server.
