saslauthd and tomcat is zimbraMtaAuthHost set? is zimbraMtaAuthURL set? Is the mode (http/https) in zimbraMtaAuthURL consistent with the port your tomcat instance is listening on? If not, reset zimbraMtaAuthHost to the value it's currently set to - this will reset zimbraMtaAuthURL (and work around a bug).
I believe that saslauthd is probably dying because tomcat is dying.
What happens when you run tomcat start? What shows up in /opt/zimbra/log/zimbra.log? /opt/zimbra/tomcat/logs/catalina.out?
After you start tomcat, try starting saslauthd. |
