I generated a certificate for both of our domain controllers using lincert.  I added both of our domain controllers under the ldap tab using secure ldap over port 636.  When I save both configurations it saves successfully. 

Issue # 1:  I tried importing users, however, the import users message just spins endlessly, however, it does import some of our users, but not all. 

Issue # 2:  When I try to enable ldap authentication I receive an error message:   Could not enable LDAP

Authentication. Ensure Domain Controller is configured for at least one of the Imported Domains.

Issue # 3:  I would like to use the free version, but was not given that as an option during the installation on Centos 7 without a gui.  How do I obtain a license for the free Standard edition?

The importssl0.txt log has the follow errors:  

[08:14:24:883]|[07-04-2019]|[com.manageengine.servicedesk.ssl.util.ImportSSLUtil]|[SEVERE]|[119]: Exception occurred when estimating expiry date of SSL certificate! : Initialize Failed|

[08:14:24:881]|[07-04-2019]|[com.manageengine.servicedesk.ssl.onpremise.server.certificate.CertificateChainBuilder]|[SEVERE]|[119]: Exception in reading keystore |

com.manageengine.servicedesk.ssl.framework.server.exception.SyMException: Initialize Failed

I don't believe there are any errors in the serverout0.txt log.

What do I need to do to resolve these issues?
