Problem Single Sign on - Portal 7.0

Hello,

we are CRM 2005 Ramp-uP customer and use for it the Enterprise portal version 7.0 (Netweaver 2004s). For the single Sign on I would like to provide the key file. But I always receive the error message that the J2EE administrator role is missing to me. Therefore the file cannot be produced. Even if I me now all ⚠️ available roles assign, remain the error message.

Does someone know this problem? Why can the key file not be produced and/or does give it a solution?

Regards
