 As per the current set-up in DevTest, it uses "lisa.http.kerberos.principal" and "lisa.http.kerberos.pass" values from 'local.properties' to drive Kerberos authentication. And if we have to change the Kerberos credentials then we have to change “lisa.http.kerberos.principal” and “lisa.http.kerberos.pass” values in ‘local.properties’ file and restart workstation to consume the updated credentials. I am reaching out to check if there is an way to override these properties value in run-time so that we don’t have to restart the components to consume the updated credentials? 
All supported DevTest versions
1. Try passing these properties from the config file. 
2.  Use a javascript step in the Testcase and set the property values there using  getStateValue and setStateValue properties
