Recently, I had a case where the zimbra site enabled ldap_starttls_supported, but was getting an error.

zmlocalconfig -e ldap_starttls_supported=1

Host zimbra-ldap.example.com
        Starting ldap...Done.
Unable to start TLS: SSL connect attempt failed error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed when connecting to ldap master.

If you are seeing this error, or something similar, start ldap as the zimbra user in debug node.

ldap stop

zmlocalconfig -e ldap_starttls_supported=1

sudo /opt/zimbra/libexec/zmslapd -l LOCAL0 -u zimbra -h 'ldap://zimbra-ldap.example.com:389 ldapi:///' -F /opt/zimbra/data/ldap/config -d -4

There will a lot of output. However, if there's an issue, the bottom portion of the output may leave a clue.

The unknown ca part of the output implies the CA bundle is not trusted. To add your CA Bundle, run the following as the zimbra user.

zmcertmgr addcacert /path/to/your/ca/bundle/commercial_ca.crt

Next, try again.

ldap stop
zmlocalconfig -e ldap_starttls_supported=1
ldap start
