Problem

Ldap servers are unable to communicate with other servers in the ZCS environment

We get the below error when checking the LDAP status

zmcontrol status
Unable to start TLS: SSL connect attempt failed error:14090086:SSL

OR

ldap status
Unable to start TLS: SSL connect attempt failed error:14090086:SSL

How to verify the Root CA has expired

su - zimbra
cd /opt/zimbra/ssl/zimbra/commercial/
zimbra@mail commercial]$ /opt/zimbra/bin/zmcertmgr verifycrt comm commercial.key commercial.crt commercial_ca.crt
** Verifying 'commercial.crt' against 'commercial.key'
Certificate 'commercial.crt' and private key 'commercial.key' match.
** Verifying 'commercial.crt' against 'commercial_ca.crt'
ERROR: Unable to validate certificate chain: commercial.crt: C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, CN = AddTrust External CA Root
error 10 at 3 depth lookup:certificate has expired
C = US, ST = New Jersey, L = Jersey City, O = The USERTRUST Network, CN = USERTrust RSA Certification Authority
error 10 at 2 depth lookup:certificate has expired
OK

Solution

This issue has cropped up because Sectigo (Comodo) Root certificate which is namely AddTrust External CA Root have expired on May 30, 2020. The successor of this root certificate is named the Comodo RSA Certification authority Root, and wil expire in 2038. We need to download the new Comodo RSA Certification authority Root and re deploy the SSL certificate.

The new Comodo RSA Certification authority Root can be downloaded from here link

Steps to re deploy the certs

1. Download and save the root CA. (e.g. /tmp/ca.crt) 2. Download any intermediary CAs from your provider to a temporary file. (e.g. /tmp/ca_intermediary.crt) 3. Combine root and intermediary CAs into a temporary file.

cat /tmp/ca_intermediary.crt /tmp/ca.crt > /tmp/ca_chain.crt

4. Move the old certs and recreate the necessary folders

mv /opt/zimbra/ssl/zimbra/ /opt/zimbra/ssl/zimbra.old
mkdir /opt/zimbra/ssl/zimbra/
mkdir -p /opt/zimbra/ssl/zimbra/{ca,commercial,server}
mv /opt/zimbra/ssl/zimbra.old/commercial/commercial.key /opt/zimbra/ssl/zimbra/commercial/commercial.key
chmod 750 /opt/zimbra/ssl/zimbra
chmod 750 /opt/zimbra/ssl/zimbra/*


5. Verify your commercial certificate.

/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial/commercial.key /tmp/commercial.crt /tmp/ca_chain.crt
**Verifying /tmp/commercial.crt against
/opt/zimbra/ssl/zimbra/commercial/commercial.key
Certificate (/tmp/commercial.crt) and private key
(/opt/zimbra/ssl/zimbra/commercial/commercial.key) match.
Valid Certificate: /tmp/commercial.crt: OK

7. Deploy your commercial certificate.

/opt/zimbra/bin/zmcertmgr deploycrt comm /tmp/commercial.crt /tmp/ca_chain.crt
** Verifying /tmp/commercial.crt against
/opt/zimbra/ssl/zimbra/commercial/commercial.key
Certificate (/tmp/commercial.crt) and private key
(/opt/zimbra/ssl/zimbra/commercial/commercial.key) match.
Valid Certificate: /tmpt/commercial.crt: OK
**Copying commercial.crt to /opt/zimbra/ssl/zimbra/commercial/commercial.crt
**Appending CA chain /tmp/ca_chain.crt to
/opt/zimbra/ssl/zimbra/commercial/commercial.crt
**Saving server config key zimbraSSLCeretificate…done.
**Saving server config key zimbraSSLPrivateKey…done.
**Installing mta certificate and key…done.
**Installing slapd certificate and key…done.
**Installing proxy certificate and key…done.
**Creating pkcs12 file /opt/zimbra/ssl/zimbra/jetty.pkcs12…done.
**Creating keystore file /opt/zimbra/mailbox/etc/keystore…done.
**Installing CA to /opt/zimbra/conf/ca…done.

8. To finish, verify the certificate was deployed.
