Configuring customized authentication form
FortiADC allows you to customize your login page with your company brand images and modify the layout/text. It also supports the 2FA token page.
Similar to the GUI of the error page, we allow the user to upload a zip/tar/tar.gz file. The file must include a logging.html file and you must use onsubmit="return Fsb(event)" in your form. It must include the tag %%auth_script%%.
If you would like to use a token, you must include the tag %%token_script%% in your web page and use onsubmit="return Fsb(event)" in your form.
To configure a Customized Authentication Form:
1. Go to User Authentication > Customized Authentication Form.
2. Click Create New to display the configuration editor.
3. Complete the configuration for the customized authentication form.
4. Save the configuration.
| Settings | Guidelines |
|---|---|
| Name | Configuration name. Valid characters are A-Z, a-z, 0-9, _, and -. No spaces. After you initially save the configuration, you cannot edit the name. |
| File | File package for customize Authentication form page. Click ‘Choose File’ to upload. |
| Username Field Name | The username field name in customize form |
| Password Field Name | The password field name in customize form |
| Virtual Path | Virtual path of customized authentication form function. This path is running on VS, so it will conflict with other configure like error page’s vpath and Captcha. |
When you choose to use a customized authorization form, LB will untar/unzip the file to /tmp/cust_auth/[vdom]/[vs name]/[auth form name]/ from /home/backup_config_file/[vdom]/cust_auth/[auth profile name].zip and add a line, FileSrv [location of untar/unzip file] [/virtual address/], to the httproxy config which will handle this line by the local file framework in httproxy.
The following is an example of a login.html file:
