Nothing frustrates me more than returning to the vRA UI, clicking something and then have it immediately log me out. This appears to be quite random a lot of the time and whilst I can appreciate that this is in the interest of security, I find it a little too aggressive. This can be changed by extending the life of the authentication cookie using the following procedure.
Log in to the vRA appliance using SSH (SSH will need to be enabled via the vRA Appliance VAMI interface if it is not already). Edit the following file:
Add the following line to the end of the file:
Where ‘28800’ is the number of seconds (8 hours) until the authentication cookie expires. Set this based on your own requirements.
Save the file and then restart the vcac-server service
service vcac-server restart
It will take the usual 5 minutes or so for the server to fully start up and once complete the new settings will be applied.
Repeat this process for any remaining appliances in the cluster.
