Is it possible to display the current node count in SMC?
Is it still right, that a Third-Party Device like a LDAP-Server has a node count of 0.2?
it is visible in Configuration > Administration > Licenses, select the Management Server license, scroll down in the info panel on the bottom. There you have "Max number of manageable components" and it lists also the current count.
Monitored third-party devices count as 0.2, see McAfee KnowledgeBase - SMC license node count calculation
