I'm running Zimbra 7.1.3 Open Source Edition, and very happy with that!
Running Zimbra on Amazon EC2-server (Ubuntu 10.04). Only issues I had was about split DNS, but used dnsmasq to fix this. All mx-records checks OK.
Everything works fine, and has been running for some months now.
I have set up a new Amazon server and installed a private MediaWiki to use for documentation. It would be great to use Zimbra LDAP to login. MediaWiki has a ldap extention that is easy to configure - or at least it looks easy. My issue starts before that.
On my Zimbra server I can use ldapsearch fine. From my laptop - or my MediaWiki server - I get:
ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
If try to telnet to my server on port 389 I get connection refused.
Telnet to other ports in use are OK.
Yes - port 389 is open in the Amazon Security Group (That is the FW) :-)
Have done to much searching about this topic without getting there. Is there somewhere in the LDAP config that only allow connections from localhost?
So - any help for getting Zimbra LDAP reachable from internet would be highy appreciated.
And also other thoughts about using LDAP like this - recommended or not?
