Yes.
First edit the file /etc/WiKID/security and add a line that says: WAUTH_PASSPHRASE="your_passphrase_to_start_the_server".
Then:
# cp /opt/WiKID/conf/templates/wikid /etc/init.d/wikid
# chmod +x /etc/init.d/wikid
# chmod +x /etc/init.d/wikid
# service wikid start
# chkconfig wikid on
If the server still prompts for a passphrase on startup, you may need to escape special characters in the passphrase. So, 'pass$phrase' becomes 'pass\$phrase'.
