User name and pw fields on the sign in page should not turn on auto capitalization. This is a common irritant seen on mobile devices. This fix also turns off auto complete and autocorrect. If the user has the browser or another service auto filling credentials, this shouldn't interfere with that.
I tried to login to freenas this morning on my iPad (iOS 12.1.4) using safari but try as I might I couldn't get the username field on the signin page to NOT autocapitalize. Could you add the autocapitalize="none" to this field to (possibly) prevent this issue? I searched through https://github.com/freenas/webui/ but could find no instances of autocapitalize.
I know I could turn off capitalize globally but that is a suboptimal solution given how broad its effects would be.
