Link to non URL or email files either in Custom or Notes Sections of User Story within Rally, ie a file located on one of our servers. Related question, if security needs to be granted how is this accomplished.
My apologies but I'm not certain I understand your question. Are you asking if you can include a link to a non-URL in the Notes field or a custom field? Do you mean a network shared folder for example?
Unfortunately, this isn't something that we can handle from the product side as most modern browsers block the ability to click on a file anchor when it is in a page being served by a web server. This is designed as a security feature of the browser to prevent malicious scripts from being able to access or tamper with local files on your machine/network.
