Symptoms

Some data such as the System manager version is missing from ACM Dashboard. 

The ACM server.log file has the following error:

2019-08-30 10:53:25,045 ERROR [Thread-65867]-util.LDAPUtil: testConnection --> LDAP connection failed for Secure connection.javax.naming.CommunicationException: simple bind failed: xxx.xxx.xxx.xxx:636 [Root exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present]

Cause

The ACM LDAP server is not configured correctly and that is causing the LDAP connection to fail.

Resolution

This is an issue with the ldapconfig.xml file on the ACM server. 

The ldapconfig.xml has the ACM IP address for the ldapHostName tag and not the ACM FQDN. The connection is trying to use the FQDN for the ACM, and it is causing the connection to the LDAP server to fail.

To resolve this issue, edit the following file with vi:

/usr/local/dataprotection/var/configmgr/server_data/config/ldapconfig.xml

Change the following tag:

Note: acmserver.domain.com is to be replaced with the FQDN of the actual ACM server.
  
<ldapHostName>999.99.99.999</ldapHostName>
To 
<ldapHostName>acmserver.domain.com</ldapHostName>

Reboot the ACM server.
