VCST-70-000019 - The Security Token Service must limit the number of allowed connections.

Information

Limiting the number of established connections to the Security Token Service is a basic denial-of-service protection. Servers where the limit is too high or unlimited can potentially run out of system resources and negatively affect system availability.

Solution

Navigate to and open:

/usr/lib/vmware-sso/vmware-sts/conf/server.xml

Navigate to the <Connector> configured with port='${bio-custom.http.port}'.

Add or change the following value:

acceptCount='100'

Restart the service with the following command:

# vmon-cli --restart sts
