Custom login base domain using GUI whitelabel themes

[hsato03]

Description

When logging in via the ACS GUI, if the user does not belong to the ROOT domain, its full domain path must be specified.

With that, the GUI whitelabel runtime system has been extended with the loginBaseDomain parameter, which allows administrators to specify a base domain for a theme, enabling users to log in without specifying the domain or by providing the domain relative path.

For example, when creating a theme specifying the /domain1/ domain as the base, instead of the user typing /domain1/domain2 when logging in, they will only need to provide domain2.

Furthermore, the new parameter only works with the commonNames parameter.

How Has This Been Tested?

1. I created the domain d1;
2. I created a theme with loginBaseDomain being d1;

(local) 👻 > create guitheme name=theme css="@import url('https://arquivos.scclouds.com.br/css-themes/scclouds-theme.css')" loginbasedomain="d1" commonnames="d1.local" ispublic=true
{
  "guiThemes": {
    "commonnames": "d1.local",
    "created": "2026-06-12T18:12:32+0000",
    "css": "@import url('https://arquivos.scclouds.com.br/css-themes/scclouds-theme.css')",
    "id": "fad8fdcb-0dc2-4c02-9f68-e7ec6c2032bd",
    "ispublic": true,
    "loginbasedomain": "d1",
    "name": "theme",
    "recursivedomains": false
  }
}

3. When accessing the ACS GUI via the d1.local URL, I verified that it was not necessary to specify the domain to access a d1 account;
4. When accessing the ACS GUI using any other URL (via IP address, for example), I verified that it was necessary to enter the domain to access a d1 account.

How did you try to break this feature and the system with this change?
