Hello there,
I normaly use the credentials option in the VCA / VCRM link. I believe the certificate option is far from workable. Is there a reason why you use the certificate instead? When you look at the development in the SUM department i think the VCRM had had it's longest time. In the latest VCA i've seen that the diskfirmware and ILO is not detected. Not a mayor issue since I click on the baseline link at the top to update the server or push from SIM.
By the way there are newer version of the VCRM 7.3.4.0 and VCA version 7.3.3.0, these only seem open SSL fixes but you never know...
Kind regards,
Andrew
