Afaria 7: enrollment a blackberry device

hi guys,

i have a problem while i try to enroll my blackberry device into Afaria server.

i think to set up the correct configuration in Afaria blackberry client, infact, when i try connect from menu, no error appear on blackberry screen (successful session at ....).

Unfortunatly, when i try Enroll option from menu, after insert enrollment code, in blackberry display occured a message: Enrollment failed: (HTTP status: 401).

Is there any ones that could help me about this issues?

thanks in advance
