Im currently working on a deployment of vRealize Suite Lifecycle Manager 8.0 It was deployed using Easy Installer method. And it has given me a few headaches to be honest. Here is the recipe on how to solve one of those issues.
Replace self-signed certificate
In vRSLCM you can easily replace the self-signed certificate on the vIDM appliance if you have previously imported it into the locker. Just go through the «Replace Certificate» prosess and do the included precheck.


You will probably get the same warning as I did. If you click finish it will replace the certificate and everything looks fine until you try «Trigger Inventory Sync» from vRSLCM. It will fail with the following error:

How to fix the issue
1. SSH to vIDM and log in as sshuser. Run the following command to become the root user. su root
2. Edit the file /etc/ssh/sshd_config and change the value of PermitRootLogin to yesPermitRootLogin yes
3. Run the following command to restart the sshd service.service sshd restart
«Trigger Inventory Sync» and it will complete successfully

This issue appears to be resolved with the 8.0.1 release of vRSLCM.
