By default ILMT, and WebSphere in general, asks you for a password when running srvstop.sh if security is enabled. That’s nice if you don’t trust your users. But, if you have a secured system you may not want to have to lookup the userid the once or twice a year you bring down WebSphere.
On a new install of ILMT, with the bundled WebSphere server, all you have to do is edit the soap.client.props file:
vi /opt/IBM/LMT/eWAS/profiles/AppSrv01/properties/soap.client.props
