To alter the look and feel of the login page for your requesters, go to Admin>>General Settings>>Self Service Portal Settings.
Under Customize login page click Customize Now.
You can make the required changes in the displayed editor; you can upload a background image, add styles, or even modify HTML file to suit your requirements. When you save your settings, the changes will be effected immediately. That is, you do not have to restart the application.
If you would like to discard all changes you made, you can click Restore to Default in the top right corner.
Note: Previously customized login page will not be displayed once you have upgraded (To versions 9418 or newer). Instead, SDP's default login page will be displayed. However, you can reconfigure it from this page. Insert your existing CSS script within the style tag (<style>CSS</style>) in the login page customization page editor. Make sure to mention {{login_form}} within div tag which has "loginFormDiv" id instead of your login form scripts. The customization done here will also reflect in the forgot password page.
