We have upgraded PAM from 4.1.6 to 4.2.0 and then applied HotFix 4.2.0.03. After this upgrade, the integration with vCenter no longer works.
If I go to:
Device -> Manage Device -> Refresh VMWare Devices
I get:
Error Error: {"data":null,"success":false,"total":0,"message":"PAM-CMN-0413: Failed to connect to VMware."}
PAM 4.2.0, 4.2.1
Upgrade to 4.2.1 fixes the issue, but you need to do this additional step :
Upload the vCenter's root certificate from PAM UI (Configuration->Security->Certificates->Upload)
Make sure to upload the root CA as a CA Bundle
