<DIV>No; in my loginhandler I just need to know wich attributes the Service
Provider needs. What I'm going to do is: </DIV>
<DIV> </DIV>
<DIV>1) the Service Provider forwards to the IDP </DIV>
<DIV>2) the IDP chooses my loginhandler </DIV>
<DIV>3) my loginhandler creates and shows a servlet. That servlet ask for
authentication AND it shows which attributes the Service Provider requires</DIV>
<DIV>4) the user than authenticates AND provide the attributes to the IDP</DIV>
<DIV>5) the authentication is completed, the attributes are PUSHED to the
Service Provider. </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>So the loginhandler needs the info about the required attributes so that
the user can provide these attributes. </DIV>
<DIV> </DIV>
<DIV>So you suggest and says that this (is only) possible with the metadata?
</DIV>
