What would be the best way to design our user base if we have over 500,000 users that may put in tickets to Jira Service Desk if they have an IT issue? We would like their accounts to authenticate and use the information from our LDAP environment, rather than be created within Jira Service Desk. We're looking at Datacenter, so JIT provisioning doesn't seem to be an option (and may cause issues of its own).
Syncing all of the users from our LDAP directory does not seem to consistently work, and requires significant resources on the servers to complete successfully.
What would be the best way to handle this situation? Is it just a matter of sizing an extremely large deployment? Look into other ways to handle these users' requests?
Thanks!
