[ ? ] Remove link “Log in using SSO” on login page

Hello!

Could you tell me, please, how I can remove link “Log in using SSO” from login page? (NADI adds this link on the login page above the “Remember me” checkbox)

I use Kerberos (transparent) authorization and the fallback to the login page is performed only if the authorization fails – this link becomes unnecessary…

It would be great if this can be done with a hook or filter, without the need to make corrections into the NADI code.

Thank you in advance.
