I was able to find the following under Directory Configuration Summary under JIRA user management settings:
"ldap.referral": "false"
"ldap.secure": "false"
"ldap.url": "ldaps://ad-ldap.amc.edu:636"
How can I enable LDAP secure to use port 636 for accessing JIRA? I found a couple articles but they are referring to older versions of JIRA and we're running 8.0.2.
