I then use the Token -> Login -> SO and provide the PIN. It responds to that with operation in progress and closes the login like it was sucessful. If I then click on Certificates it gives me a red status bar "C_OpenSession returned CKR_SESSION_READ_WRITE_SO_EXISTS".and under basic info it tells me rw-count =1 r-count=1.
