customize APM login page with forgot password link

You can add it in the customization section.

Access Policy

Customization

Advanced

Then you can edit the logon page found down the line from Access Policies >> [Profile Name] >> Access Policy >> Logon Pages >> Logon Page (logon page name) >> login.inc.

There's an example in the APM Customization document (it talks about adding an image, but could be used to add something different as well.)

Hope this helps.
