Portal 7.3 - Authentication Schemes and portal logon page .xml

Hi,

I create a custom logon page logonJass.ear on portal 7.3 and a custom login module for a custom Iview.

I put the logonJass.ear on Authentication Schemes but that don`t work.

i try

<frontendtarget>logonJaas</frontendtarget>

or that

<frontendtarget>logonJaas.

certlogon

</frontendtarget>

Thanks for your Help
