Hello Andre,
Could you kindly ensure that you've correctly created the credentials for SAPSNCSKERB.pse?
sapgenpse seclogin -p <path>\SAPSNCSKERB.pse -x <PIN> -O <system_user>
you can verify that with command:
sapgenpse seclogin -l
(if possible, please place us the output of this command too).
Best Regards,
Guilherme de Oliveira
