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 [Bug 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: [SOLVED] Expired Cert in 5.0GA can cause mail Delivery failure Alternate: Argh Commercial Certificates after a 4.10 -> 5.0 FOSS upgrade!


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
