Dec 21 13:47:54 kes su: kes to root on /dev/ttyp5
Dec 21 13:47:58 kes kes: /r/svnserve: DEBUG: checkyesno: svnserve_enable is set to YES.
Dec 21 13:47:58 kes kes: /r/svnserve: DEBUG: run_rc_command: doit: su -m svn -c 'sh -c "/usr/local/bin/svnserve -d
--listen-port=3690 --foreground -r /var/db/trunk"'
Dec 21 13:47:58 kes su: pam_acct_mgmt: authentication error
