Revision as of 00:41, 7 January 2008

There are some issues in Zimbra 5.0 GA that you should know about.

Zimbra can install/upgrade and work under most circumstances, however, a small number of users are encountering some issues.

We wanted to post this thread to let you know about these, and help you work through any issue you have.


Issue:

Problem with Certificate can cause MTA Failure [ http://bugzilla.zimbra.com/show_bug.cgi?id=23253 ]

Symptom:

When MTA starts up, user will receive the following message in the /var/log/zimbra.log file:

Error:
  postfix/trivial-rewrite[6172]: fatal: ldap:/opt/zimbra/conf/ldap-vad.cf(0,lock|fold_fix): table lookup problem
  postfix/trivial-rewrite[19377]: fatal: ldap:/opt/zimbra/conf/ldap-vad.cf(0,lock|fold_fix): table lookup problem
  postfix/trivial-rewrite[19378]: error: dict_ldap_connect: Unable to set STARTTLS: -11: Connect error


Then the MTA (postfix) will stop functioning resulting in mail delivery failure (via lmtp and smtp).

Common Cause:

CA chain can be appended in reverse creating invalid Certificate

Workaround:

Read this post: http://www.zimbra.com/forums/administrators/13927-if-you-have-trouble-zimbra-5-0-read.html

Alternate: http://www.zimbra.com/forums/installation/13898-argh-commercial-certificates-after-4-10-5-0-foss-upgrade.html


   Steps:
   (a) Run as root: cd /opt/zimbra/ssl; mkdir bak; mv * bak
   (b) Run this as zimbra:
   (b1) To get the password: zmlocalconfig -s zimbra_ldap_password
   (b2) ldapmodify -x -h fqdn.server.tld -D "uid=zimbra,cn=admins,cn=zimbra" -W
   Code:
   dn: cn=config,cn=zimbra
   changetype:modify
   delete: zimbraCertAuthorityCertSelfSigned      [Hit Enter Twice here]
   ^D
   (b3) ldapmodify -x -h fqdn.server.tld -D "uid=zimbra,cn=admins,cn=zimbra" -W
   Code:
   dn: cn=config,cn=zimbra
   changetype:modify
   delete: zimbraCertAuthorityKeySelfSigned      [Hit Enter Twice here]
   ^D
   (c) as root: run /opt/zimbra/bin/zmcertmgr createca
   (d) as root: run /opt/zimbra/bin/zmcertmgr deployca
   (e) as root: run /opt/zimbra/bin/zmcertmgr install self -new
   (f) as root: su - zimbra zmcontrol stop; su - zimbra zmcontrol start
   ^D is Control-D

For Multi-Server: Run this on the system which is running postfix or an ldap replica

After doing the steps listed above on the ldap master, log into any different systems running postfix or that are an ldap replica and:

   (a) Run as root: su - zimbra zmcontrol stop
   (b) Run as root: cd /opt/zimbra/ssl; mkdir bak; mv * bak
   (c) Run as root: run /opt/zimbra/bin/zmcertmgr createca
   (This will download the new CA from the LDAP server)
   (d) Run as root: run /opt/zimbra/bin/zmcertmgr deployca 
   (e) Run as root: su - zimbra zmcontrtol start
