As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Everything seems to be in place for authbind to work, but Alfresco 3.3g IMAP fails to bind to port 143. Binding to unprivileged ports works fine.  Anyone have success binding to  privileged ports with Alfresco 3.3g?

/etc/default/tomcat6 line 60: AUTHBIND=yes
/etc/authbind/byuid/107 (tomcat UID)= 0.0.0.0/32:1,1023 (also tried removing this file and creating /etc/authbind/byport owned by tomcat6 user

In alfresco-global.properties:
#
# IMAP
#————-
imap.server.enabled=true
imap.server.port=143
imap.server.host=(hostname which resolves to local IP address)

web.application.context.url=http://FQDN:8080/alfresco
imap.server.web.application.context.url=http://FQDN:8080/alfresco

tomcat6 init script excerpt:

catalina_sh() {
   # Escape any double quotes in the value of JAVA_OPTS
   JAVA_OPTS="$(echo $JAVA_OPTS | sed 's/\"/\\\"/g')"

Failure to bind is not logged in alfresco.log, but /var/log/tomcat6/catalina.out and error is:

Exception in thread "Thread-29" java.lang.RuntimeException: java.net.SocketException: No such file or directory
        at com.icegreen.greenmail.imap.ImapServer.run(ImapServer.java:53)

By Default, the file /etc/authbind/byuid/107 contained:

0.0.0.0/32:1,1023

The fix is changing this to:

x.x.x.x/32:1,1023

where x.x.x.x is your local IP address which resolves to your systems hostname.
