Fix Recommendation

Navigate to and open:

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

The STS service has 2 connectors with the below pairs of ports and addresses.

Navigate to the target <Connector> node and configure the port and address as follows.

port="${bio-custom.http.port}"
address="localhost"

port="${bio-ssl-localhost.https.port}"
address="localhost"

Restart the service with the following command:

# vmon-cli --restart sts

Note: The connector with port="${bio-ssl-clientauth.https.port}" should not have address set.

Check Contents

At the command prompt, run the following command:

# xmllint --xpath '//Connector[not(@port = "${bio-ssl-clientauth.https.port}") and (@port = "0" or not(@address))]' /usr/lib/vmware-sso/vmware-sts/conf/server.xml

Expected result:

XPath set is empty

If any connectors are returned, this is a finding.
