 Solaris

-Currently, sshd does not support BSM auditting.  This can show up as errors
-when editting cron entries via crontab.  See.
-http://bugzilla.mindrot.org/show_bug.cgi?id=125
+If you enable BSM auditing on Solaris, you need to update audit_event(4)
+for praudit(1m) to give sensible output.  The following line needs to be
+added to /etc/security/audit_event:

+
+The BSM audit event range available for third party TCB applications is
+32768 - 65535.  Event number 32800 has been choosen for AUE_openssh.
+There is no official registry of 3rd party event numbers, so if this
+number is already in use on your system, you may change it at build time
+by configure'ing --with-cflags=-DAUE_openssh=32801 then rebuilding.
